In all 493 freshwater and 301 marine water samples were analyzed for the presence of fecal coliforms. Farms, scattered housing and forestry are the predominate land uses. The project objectives were: - Characterize the levels of fecal coliform bacteria in the watersheds and establish baseline levels of fecal coliform. Estimate the fecal coliform loading into the receiving marine waters. Evaluate the pollution levels and probable sources from the water quality data. Soils in the area consist of a wide variety of material that were brought here from glacial systems 12,000.and 15,000 years ago. As a result of this glacial activity, drainage is generally fair although some areas do emist that consist of hard pan soils, creating poor drainage. Rainfall varies from seventeen inches annually at the north end of the county to sixty inch at the south end of the county near Brinncn. Headwater stations generally had much lower levels of fecal coliform than reaches with residential or agricultural development along the corridor. Consistent violations of the Washington State Water Quality Standard existed in Salmon Creek, Houck Creek, Snot Creek, Andrews Creek, Zerr Drain, Chimac m, Creek (both east and west fork) and, Na.ilors Creek (more than 50 fc /100ml and > 10% of the samples > 100 fc /100ml). Associated with creeks that had high pollution levels in lower reaches were agricultural practices, particularly those where dam ticated animals had direct access to the water.. In reaches where domesticated animals had access to the creek /streams bank erosion occurred, manure was found in the water and both fecal coliform concentration and loadings from the cree—k. increased markedly. In general, marine stations at -the head of the bay had slightly elevated bacterial *.levels over thoes.stations located toward the mouth of the bay. Periodically, extreme elevated levels occurred near the fresh water sources in Discovery Bay and Port Townsend Bay. These elevated levels are most likely due to poor animal keeping practices in and around creeks. Recent logging activity. in the Discovery Bay watershed may be related to the flooding which has occurred. in the post logging years at, Salmon . and. Snow Creeks. Flooding of pastures can lead to increased levels of coliform pollution and may threaten shellfish harvesting at the head of Discovery Bay. Part Ludlow Bay experienced a marked increase in fecal coiiform levels in July at the end of heavy recreational boat use. t The relationship between land use and bacteria levels are fturaclu1areas assess: hcwever, stream reaches that flawed through agricultural generally found to have been adversely impacted. Marine water stations near freshwater sources bad increased levels of fecal coliform. r. 5 This project benefited from the participation and support of a number of individuals and agencies and special thanks are due to the following: Support for this project was provided through a grant from the Washington State Department of Ecology.

B G t iNS•6' N The positive relaticnship.between sewage pollution of shellfish growing areas and disease has been demonstrated many times (Verber, 1984; Richardson, 1985). Shellfish -borne infectious diseases are generally transmitted through a fecal -oral route. The pathway can became circuitous. The cycle usually begins with fecal contamination of the growing waters. Feces deposited on land surfaces can release pathogens into surface waters through run -off. Most fresh waters empty into an estuary where fecal bacteria and viruses may accumulate in the sediment and may subsequently be resuspended into the water column (Er_tienbrecher, 1981). Recent studies in Puget Sound and Hood Canal have found bacterial contamination to exist in marine waters at levels that violate the state water quality standards. Investigations by Cook (1984) found that the head of Quilcene Bay was contaminated with fecal coliform bacteria, making shellfish from that area unfit for human consumption. Subsequent investigaticns by Welch and Banks (1986) in the Quilcene /Dabob Bay's had similar fi ink. In addition to their marine water work, they examined fresh water sources entering the bay and the sanitary conditions of septic systems of residents near both fresh and marina water. Their study concluded that stream reaches with little or no development upstream were gener-ally found to have high water quality and within state standards. Lower water quality existed in reaches which flow through developed areas. Agricultural practices were found to contribute to conditions which violate state water quality standards. The impetus of this ccun- y -wide project was from the presumption that similar situations may exist in other areas of the county. The county wide water quality monitoring program in Eastern Jefferson County started in January of 1988 to Tebruary 1989 and has established baseline fecal coliform data for five bay's and their fresh water sources. In all, 493 freshwater and 301 marine water samples were analyzed in the county's laboratory for fecal coliform contamination. t Y In the process of this investigation several stream reaches were identified as having, high levels of fecal coliform. These elevated levels were most conspicuous in stream reaches that passed through agricultural areas. Although the scope of the project was not correction oriented, several of the land owners were contacted and made aware of the bacterial impacts on water quality from their management practices. Several of these individuals agreed to meet with the District Conservaticnist to discuss Best Management Practice (BMP's). The Soil Conservation Service then offered assistance to the individual to mitigate or correct the bacterial pollution problem and other impacts that were `affecting water quality. , 7 Characterize the levels of fecal coliform bacteria in the watersheds and establish baseline levels of fecal coliform. Estimate the fecal colifor..t loading into the receiving marine waters. Evaluate the pollution levels and probable sources from the water quality data. .. There is a wide variety of parent material that make up the soils of Eastern Jefferson County. The bulk of these hete_Togenous materials were diverted here from two large glacial systems occ=--i g 12,000 and 15,000 years ago. 'TIhe first was the Olympic Glacier, which moved down from the Olympic Morcrntairs on the east side. Glacial materials were deposited mainly along Hood Canal to an elevation of approximately 200 to 300 feet. The second system was the Great Continental Glacier, which moved to this area by meandering through the mountains of Western Canada. This system brought great gt-,antities of outwash which consists of medium course textured gravel atxi stony material below the surface of the soils and is highly permeable allowing for good drainage. Glacial till or hard pan consists of unconsolidated clay, sand, gravel and rocks which have been compacted by the weight of the glacier into a highly impervious concrete- like material and does not allow good drainage. Climn e - The climate in the project area is of a marine type, characterized by suers that are generally cool and ccmcaratively dry, with winters that are rather mild and wet. Given the physiology of the Olympic Mountains and the origins of the low pressure stores off - shore, great quantities of precipitation fall on the wirdzrra.rd side of the mountains. Lee-ward of the mountains, kmcwn as the Olympic Rain Shadow, there is a small area of low precipitation in much of the project area, including Discovery Bay arxi Port Townsend Bay. At the.south end of the county, near Brinnon, in the outer reaches of the rain shadow, - the average ar= l rain fall can be more than sixty inches per year. The average armual rainfall at the_ northern end of the county near Port Townsend is approximately sateen inches per year. Rain fall data used was collected at the Snow Cl--,-,k Research Station and has been used to represent rain fall through the project area. The rainfall during the project was generally less than the mean rainfall (Figure 1, 2). 8 , ,lJf C;;INAACUM MIR l7T.71 Si�•L:1JIV11�t1CivV �� f -'.:AT =C *4 I I . xrcT VtGOLEW -- , . �. - - -- -- LUDLOW �.

BenefJC:ial Uses Beneficial imses for marine waters are described in the water quality standards for waters of the state of Washington (chapter 173 -201, WAC). These uses include supplies for domestic, or agriculture purposes; fish, shellfish, and wildlife habitat; recreation and navigation. The water quality standards set forth in WAC 173 -201 are established in conformance with present and potential uses of the surface waters. For fecal coli:E the state standard is as follows: CUSS AA (extraordinary) water: Freshwater: fecal coliform organisms shall not exceed a geometric mean value of 50 0rgardsms /100 mL, with not more than 10 percent of the samples exceeding 100 organisms /100 ML. Marine water: fecal coliform organisms shall not exceed a geometric mean value of 14 organic /100 mL, with not more than 10 percent of the samples exceeding 43 organisms /100 mL. CUSS A (excellent) water: Freshwater: fecal coliform organisms shall not exceed a geometric mean value of 100 organisms/100 ML, with not more than 10 percent of the samples exceeding 200 organisms /100 ML. Marine water: fecal coliform organisms shall not exceed a geometric mean value of 14 organisms/100 mL,. with not more than 10 percent of the samples exceeding 43 organisms /100 ML. As is noted, the fecal coliform standard is the same for either class of marine water; however, fresh water standards are different. 10 Ambient M=iitoring The goal of this study, as is typical of baseline documentation, involves the collection of data which is used to characterize and describe conditions that exist before action is taken. The focus of this project was oriented toward shellfish protection through the establishme.*it of baseline fecal coliform levels in both the fresh and marine waters. Although fecal coliform (fc) bacteria typically are not pathogenic, it is the indicator used to evaluate shellfish growing waters for bacterial pollution and the presence of pathogenic organisms. This indicator is used as the standard for shellfish by the U.S. Food and Drug Administration (FDA) and the Washington State Department of Social and Health Services (DSi3S) to determine the suitability of the water for the harvesting of shellfish. Waters that violate the standard are subject to closures. Fresh water ambient stations were established to brac1cet stream reaches with samples collected at the mouth, at changes in land use, at heaters and at their significant tributaries. A11 watershed systettis monitored were examined as an individual basin, however, the same investigative procedure was used for each watershed system. Fresh water samples were typically collected before marine samples with as little delay as pcssible given laboratory constraints, tides and weather conditions. At the mouth of creeks and rivers replica samples were taken and single samples were taken at all other stations. A total of 493 freshwater and 301 marine water samples were analyzed for fecal coliforms . Fecal coliform conditions were evaluated using two methods, concentration and loading. It is important to note the difference between these terms prior to reviewing the findings. . Concentration is defined as the number of coliform organisms in 100 m1 of water. Load nu, on the other hand, refers to the total number of fecal coliform organisms that flow d)vm a stream over a twenty -four hour period. Loading provides a means of making a quantitative comparison between streams. Fecal coliform loadings are presented in 10 "9 (Billion). The formula used to conduct loading calculations is based on the equation from Kittrell (1969) as follows: FC LcaH (FC Per Day) = (FC) x Q x 0.0246 where: (FC) = fecal coliform count per day and: Q = stream flow in cubic feet per second (cfs) Stream flows were measured with a Marsh- McBirney water current meter Model 201 -0 and were taken at the lowest station on each stream and the major tributaries. The stream flows were calculated by measuring the velocity at a cross section of the stream corridor. The discharge formula used for cfs ccmzutatioa is Q = Z(a v) 11 Where Q is the total discha e, a is an individual subsection area, and v is the corresponding mean velocity of the flow of a subsection (Rantz, S.E., 1982). For the marine waters, ambient monitoring stations were established to coincide, as much as possible, with stations that the DSHS have used previously. Results fran the DSrIS studies were considered when establ sh ' stations. Due to laboratory constraints, single water samples were taken at most stations; however, at the head of bays near fresh water inputs replicas were taken. Recorded at each station was the surface temperature and salinity using a Bec'_aman salinometer Model RS5- 3. Sampling was conducted at both fresh and marine water stations and then taken to the laboratory for processing and enumeration of fecal coliform bacteria. In both cases, samples were collected from the surface (not more than three inches below the surface) of the water. A11 samples were kept at temfleratures between four and ten degrees ceisius. The elapsed _ time between collection and inoculation was less than twenty four hours, and typically inoculation occurred within twelve hours of collection. At the start of this project laboratory support from DSHS was available for marine water analysis. After preliminary sampling in the selected bay's was conducted, laboratory support from DSHS was recinded. To this end the county had to reduce the monitoring program and begin analysis in its laboratory. For laboratory quality assurance of water analysis, laboratory splits were conducted. Samples were collected in sterile plastic Z.iploc sanC uich bags, m=ced thoroughly and 100 m1 were decanted into two separate 100 m1 sterile Nalgen collection bottles. One of these sample lots were returned to the county's laboratory for most probable rnmiher (MEN) analysis, and the second lot was sent to The State Public Health laboratory in Seattle for MFN analysis. Marine samples were analyzed using the MFN, a five tube decimal dilution series. fresh waters were analyzed using membrane filtration method with MFC dehydzated media and using the analytical procedures described in Standard Methods (1980). Data Stor6cr— and Analysis As a measure of current water quality conditions, the Geometric loan Value (GM7) for each _station was -used for each season: wet, dry and the c =dative ( listed as "all" under season ham i nom) was used. The GW is. used to na malize the values (fecal coliform organisms grow gecmetrically). For marine counts when no positive tubes were observed a co=t of zero was recorded, although the minim,m, detection level is 1.8 fecal coliform per 100 ml. This recording method was used in order to be consistent with previous studies conducted in the county. 12. To obtain the G.W's one was added to each count to allow the logarithmic transformation of zero counts. The counts were then transformed `to their logarithmic value. These were then added and the sum was divided by the M=ber of counts. This average was;.then retransformed and the one was subtracted, yielding the GIV. The terms "dies" or "violation" appears on all sun=a y tables and refers to whether or not the station meets the Washington State Water Quality Standard (WAC. 173 -201). This WAC has been interpreted to read ' that both parts (i.e., the concentration per 100 m1, part 1; and the % > 100 for fresh and 43 for marine water, part 2) must fail to be in violation of the standard. The coefficient of variation (COV) was determined for each station to be used as a measure of the natural variance of samples taken at the station. The COV at each station was calculated by dividing the standard deviation of the log transformed data by the mean of the log transformed data 13 RESULTS AND DIS=ICJN The results and discussion section of this report are divided into two parts: 1) Ambient monitoring results for both fresh and marine water investigation; 2) Loading levels frcan fresh water. Laboratory splits and results for quality assurance are listed in appendix A. On all streams and creeks, station number 1 was the furthest downstream and station numbers increased at higher elevations in the watershed. In addition to the results, station locations are provided. These descriptive station locations have been included to provide workers in the near future as much information as possible. It is expected that corrective actions will be taken in problem stream reaches in the near future. Because of the large number of bays and stations monitored, results are given first for fresh water and followed by the marine stations. The watershed systems (ie, both the fresh water basin and the estuary) will appear in the following order: Discovery Bay, Port Townsend Bay, Mats Mats Bay, Port Ludlow Bay and Jackson Cove. The data given for the cmnilative Geometric Mean Value (�iV) is presented as all on the table under the season heading. Common to all bays monitored in this project is the class rating of AA (Extraordinary), with the exception of part of Port Tovmsend Bay which has a portion of it classified as "A" (Excellent): All of the fresh surface waters monitored during the project are classified as Class AA. Figure 1 shows eastern Jefferson County and the location of the bays covered in this project. Data for commercial shellfish growing areas were obtained frcan the Annual Inventory of Commercial and Recreational Shellfish Area (DSHS, 1988). The certification process for commercial shellfish harvest is exclusively the responsibility of the Department of Social and Health Services and the County cannot and does not participate in that process. However, the County Health Department dries participate in the process to determine the suitability for recreational shellfish harvest. The objective of this project was to establish baseline data concerning fecal coli-form levels in the watershed; including both fresh and marine water. It is hoped that through action and information contained in this report that future closures of shellfish beds can be avoided. Listed in conjunction with bay characteristics are the important fresh water sources and beneficial uses. Information concerning fresh water is given first, followed by marine water. Listed below are characteristics and beneficial uses for each bay. DISCOVERY BAY SYSTEM Discovery Bay Cbara,cteristics: Class "AA° (Extraordinary). Shaw Creek and Salmon Creek are medium size fresh water sources at the head of the bay and are separated by approximately 200 meters. Snow Creek has a drainage basin of 14,784 acres and salmon Creak has a drainage basin of 12,032 acres (Richardson, 1962). Both of these creeks support important 14 '1 ry JO --T i r t /b , o 62, 1 mt �t 3t r xi rt° 1 Qt <t 1 i 1 1 1 1 1 t 1 ra.a r i G1 LAND 1 ...�a�s and 2 1 C 5 _ And 3 And Andrews Creek `� p,rcws Sa Salmon Creek Sn Snow Creek �.'

Andrews Creek, a tributary of Snow.Creek, has a drainage area of 4,691 acres arid. has a significant run of Coho spawners. However, John Bolton, a resident of the Andrews Creek area, has mentioned that he has not seen fish spewing in the creek for years. Contractors Creek, a small fresh water flow, emoties at Carr Point on the west shore of the bay. Land use of the entire drainage area is roughly forty percent timber, forty percent clearcut, ten percent residential, urban, commercial and ten percent agricultural. Agricultural areas are located at the head of the bay and follow the creek corridors of Snow, - Salmon and Andrews Creek. There are five commercial shellfish operations harvesting both clams and oysters from the bay. On the west shore commercial areas occur from Carr Point to Kalset Point, and on the east shore from Beckett Point south to the Fairmount area. There are a total of 9,139 acres of approved shellfish beds. Harvested species in 1987 include Butter Clam, Cockel Clam, Horse Clam, Native Littlenecks totaling 541,232 pounds, and a value of $400,977.60. For 1988, species harvested includes Butter Clam, Horse Clam, Manila Clam, Mud Clam, Native Littleneck totaling 343,574 pounds and a value of $332,426.95 (Word, 1989). FRFSHKATER Contractors Creek drains an area of 1,670 acres with the head water originating from springs at an elevation of 475 feet and is about 2.9 miles in.length. This creek empties into the bay on the west shore at Carr Point. There is very little agriculture in this drainage, and there is a moderate amount of timber production in the watershed. Station CT1 is below Old Gardiner Road cut-off,-near the mouth at Carr Point. The water quality here is well within standards, with a cumulative GAV of 15.59 with no samples being greater than 100 fc (fecal coliform) /100 ml. On the west side of highway 101, near the bridge, station CT2 had a cumulative CxDW of 13.93 fc /100 ml and none of the samples greater than 100 -fc /100 ml (Figure 4, Table 1) The area of the Creek that flows between CM and CT2 has a relatively wide flat basin, primarily wooded with a upper campy that shades the sun; and consequently there is sparse under growth. Residents have noted deer frequently using this area. Deer were noted in the immediate area of CTl,in approximately 50% of the visits to this station. The terrain at C72 is much steeper and more heavily vegetated with under growth. Although deer have not been recorded at this area during sample collection periods, tracks have been noted, but not as numerous as at CT1. 16 60 to M •10 0 0 W 30 J W 1 W J U �'J 10 C FECAL COLIFORNI CONCENTRATION CONTRACTORS CREEK F A M J_.

The creek empties into the head of Discovery Bay on the west shore. The primary land use in the lower reaches (below SA3) is agriculture (Figure 3). Above SA3 the land is principally managed for timber production. Station SA1, located at the Highway 101 bridge, has a cumulative GW of 84.96 fc /10Cm.1 with 31.58% of the samples greater than 100 fc /100 m1, thus failing both parts of the state water quality standard. The area from SA-1 to SA2 is flat, has a sparse canopy cover and very little elevation gain; in fact, part of the pasture immediately above SAl is tidally inundated at high tide. On the east side of West Uncus road, Station SA2 had a cumulative CAN of 17.04 and 20% of the samples being greater than 100 fc /100 ml; these levels comply only with the first part of the standard, however, and the second part is in violation. The creek reach. between SA2 and SA3 has the most elevation gain between the stations and also therp.are frequently animals along the corridor and A has-moderately dense canopy cover. Approximately 100 meters below SA3, Houck Creek, a small volume creek, empties into Salmon Creek. The cumulative aW of SA3 had 9.55 fc /100 ml with none of the samples being greater than 100 fc /100 ml (Figure 5, Table 2). Above this station the terrain becomes steeper with no agricultural activity above it and much of it has been logged. . Diverted frcat its natural course in the early 1960`s, Houck Creek now empties approximately 100 meters below station SA3. The cumulative QW at HO1 is 53.99 fc /100 ml and 35% of the samples are greater than 100 fc /100 ml. From this station to H02 is approximately 100 meters through the pasture. On the up- creek side of the fence about 3 meters, next to the cistern used by residents for drinking water, is station H02. Here the to levels drop sharply from that of the lower station to a &W of 7.58 fc with none of the samples at this station being greater than 100 fc /100 ml. As Figure 6 shows, the levels are low at H02 and have a relative narrow range of distribution while thoes at HO1 having periodically elevated* levels. As listed on Table 3, fecal coliform concentrations of HO1 vary greatly between sampling at this station. During sample collection at this station animal activity in the pasture was recorded. Periodically the land owner rotates the herd to other pastures not on this Creek and consequently, the fecal coliform levels dropped sharply. On February 9, March 22, June 13 and- July 13, 1988, cattle were recorded in the pasture, and invariably there were several watering at the creek and periodically standing in it (Figure 6, Table 3). These dates have the highest concentration levels of fecal coliform organisms during the project.

Snow Creek has a drainage basin of 14,784 acres, making it the largest drainage basin in the Discovery Bay-system. The headwaters originate from springs at 2,575 feet and travels 10.1 miles to the bay where it empties in the west shore at the head of the bay. There is a great deal of agriculture following the- Creek corridor, especially in the area near the head of the bay. At the mouth of the creek, above tidal influence and near an abandoned railroad tressle, is station SNI (Figure 3). The cumulative &W is 63.46 fc /100 ml and 33.33% of the samples greater than 100 fc /100 ml, failing both parts of the standard. The creek passes under Highway 101 and then parallels it on the west side for several miles. Station SN2 is located on the east side of West Uncus Road at the bridge crossing. At this station the bacteria level drops to half of that at SN1, to a cumulative GdV of 30.42 with none of the samples greater than 100 fc /100 m1. The road continues to parallel the creek to SN3, 5 meters up -creek of Andrews Creek tributary. At this site the cumulative CxW is 15.2 with 12.5% of the samples greater than 100 fc /100 ml. From this station. Snow Creek continues through a trailer park development paralleling the dater corridor and sweeps to the west to SA4. This station had the lowest cumulative GAV of 9.81 with no samples greater than 100 fc /100 ml (Figure 7, Table 4). 411 stations on this creek showed a marked increase in fecal coliform densities be Lheen dry and we-r season. From z` ;s station up, the elevation increases rapidly and there is no further agriculture or residential activity. ArArews Creek is the second to the smallest watershed with a drainage basin of 4,691.2 acres. With head waters starting at an elevation of 975 feet and flows 4.1 miles into Cocker Lake, located on the west side of highway 101; after leaving the lake at the north end, the water then passes through a culvert under Highway 101 and empties into Snow Creek 5 meters below station SN3 (Figure 3). At the culvert crossing on the east side of the highway 101 is station AND1 had a cumulative GN of 33.56 and 30% of the samples greater than 100 fc /100 ral. At the south end of Crocker bake, the Creek turns slightly westward until it passes under Highway 101 and then continues to follow the highway. Station AND2, where the creek flows under the highway, had a cumulative G4V of 16.56 and 14.29% being greater than 100 fc /100 ml. Station AND3 is located on the west side of Boulton Drive. This station has the lowest fecal coliform concentration of all stations on the Creek; a cumulative GMV of 14.72 and none of the samples taken being greater than 100 fc /100 ml (Figure 8, Table 5). As Figure 3 illustrates, there is a great deal of farm land along the Snow Creek corridor. During a stream walk in the fall of 1988 it was discovered that the Creek had several extended areas of unfenced stream corridor and in several. places significant portions of the stream bank have been eroded by cattle accessing the creek. During the survey no animals were recorded in the water, however there were fresh hoof marks and ma=e both in the Creek and on the Creek banks and gravel bars. 22 zoo 190 180 170 too 1150 140 J 1 z O 0 12C G 11C 1 CC J 9( w W J U � G a FECAL COLIFORM CONCENTRATION zoo 190 Ito ' loo 1e0 150 t A+i J :2 1.30 O O 1317 11C a lv'C J 9( w w 3E J 7t U 1 F M A M ' . - ® AND 1 1988 �?

SummaSummary mok }_ (ARID = Andrews Cree 25 Lower reaches of the creek (immediately above SNI) have had pigs in the water -gray an n=aearous occasions. These activates are likely responsible for significant amounts of the pollution.in the Creek. r In 1986 -87 residents have noticed flooding occurring on the low lands of both Salmon and Snow Creek. The most significant change that took place was the logging of 1,000 contiguous acres in the upper Show Creek watershed. In the upper_ watershed of Snow Creek several large log jams were discovered shortly after logging (Cooper, 1989). Shortly after the logging, county engineers noted that culverts in the Snow Creek area were suddenly tenable to handle the drainage demand that they had handled historically. In addition, there has been an estimate of 6 inches of bed deposition material (Nesbitt, 1989). The Zerr Drain is not a drainage basin in the general sense, but rather, its origin is the residual bleed -off from an artisan well. The length in its entirety is no more than 300 meters. Fran its origin at the well house, it flaws along Highway 101 for about 50 meters where it then passes under SR 20 and then flows unfenced through a pig farm. At station Zerrl, below the faro and an the north side of an abandoned railroad trestle, a cumulative G�IV of 762.70 and 93.75% of the samples taken were greater than 100 fecal coliform. Station Zerr2 is located at the well- house and has a GW of zero with none of the samples greater than 100 fc, indicating clean, pure water at its origin and heavily polluted after passing through 50 meters of the pig farm. (Figure 9, Table 6). Pigs and cattle have had unrestricted access to the water and have caused significant levels of pollution. All stations on all creeks *showed an increase in fecal coliform densities between dry and wet season (except Zerr Drain) with higher levels at the mouth than at the headwater station. The residential population in these watersheds are moderately sparse and not typically in contact with the waterway. Based on this and on field records, stream survey and the level of the fecal coliform in the water, the bacterial pollution is most likely resulting from agricultural surface runoff and domestic animal activity in and around the water way. MARINE WATER Discovery Bay had six ambient stations that were monitored over the project period (Figure 10). Station Discol is centrally located under the power line at the head of the bay. During low tides this station is an exposed mud flat. At station Discol the cumulative GW of 3.76 with 7.69% of the samples: greater than 43 fc /100 ml._ Station Disco2, located on the west shore, -had a cumulative G V of 1.16 and no samples were greater than ; 43 fc /100 ml. On the east shore, station Disco3 had a cumulative GW of 1.64 with none of the samples greater than 43 fc /100 ml. Station Disco4, located in front of Discovery Bay Resort, had a ctumilative GMV of '1 42 with 10% of the samples greater than 43 fc /100 ml. In the Aldenoa Beach area off the dock 10 meters station Disco9 had a cumulative G4V of I with none of the samples greater than 100.fc /100 ml. Off Carr Point, an the west shore, Discoll had a cumulative GMV of .37 with none of the samples 26 J 0 � N 4" C W 0., u v ] J W W v J U 1.9 1.5 1.7 1.6 1.5 1.4 1.3 1.2 1.1 1 0.9 O.� O.i 0.: O.- 0.: O.: 0.

The higi�est GMV for fecal coliform was at the head of the bay, station Discol; other near by marine stations did not shrew increased levels of fecal coliform in association with Discol. These high counts were recorded on Parch 19 and June 14, 1988 (Figure 11, Table 7). One resident has stated that there are numerous marine birds (predominately gulls) that frequent the mud flat at low tide and may be a significant ccritributor to the periodically elevated levels at station Discol. In a area similar to Discovery Bay, Determan et al. (1985 and references therein) found that there was no significant relationship betw--en bird in=bers and fecal coliform levels in either the marine water or the shellfish. Elevated levels at the head of the bay are most likely due to poor agricultural practices in and around streams which then carry the contamination into the marine water. 32 Port Townsend Bay System Part Tcvasend Bay Characteristics: Class "AA" (Extraordinary) y) /Class "A" (Excellent) . There are presently two point discharges into Port Townsend Bay. The Port Townsend Paper Canpany is the largest, discharging treated industrial and sewage effluent. The second point discharge is from the selvage treatment plant at -the Indian Island Naval Base, off Crane Point, which emits about 0.02 MS (Broadherst, 1988). Emptying into the bay on the west shore near Irondale, Chimacum Creek has a drainage basin of 21,504 acres (Richardson, 1962) and is recognized as the largest producer of Coho and Chum salmon of the watersheds dicussed in this report (Coccoli, 1988). The land use is roughly fourty -five percent timber, twenty percent clearcut, fifteen percent agricultural, ten percent urban and ten. percent cleared subdivision .Agricultural lands exist along nearly all of Chimacum Creek basin floor and following the creek corridor. The area of this bay which receives the lower class rating of "A" is that portion of trs bay west of a line from Point Hudson south to Kala Point (Figure 14). There are three areas of the bay that are classified as prohibited 4Uch does not allow commercial shellfish harvest. Two of these prohibited areas are mandatory due to the proximity of a sewage out -fall or a boat harbor in the immediate vicinity: first is Point Wilson south to the Port Townsend Boat Haven; and second is off Crane Point, on the west shore of Indian Island where a sewage out -fail is located. The third prohibited area, located at the mouth of Chimacum Creek, has a closure zone of a 1/4 of a mile in diameter at the mouth as a result of high fecal coliform levels from the Creek (DSHS, 1986). Located near the Port Townsend Marina is a salmon net pen farm that has float pens measuring approximately 500 by 500 by 25 feet. In 1987 the total weight of all fish harvested was 214,447 pounds; in 1988 the annual production was 150,000 pounds, -and for 1989 the harvest is estimated to be around 50,000 pounds. The species of fish include Chinook, Cohn, Donaldson Rainbow Trout and Atlantic trout. Harvested shellfish species in 1987 include Manila Clam, Mussels, Native Littleneck and Pacific Oyster; totaling 192,075.0 pounds for a value of $220,843.06. Species harvested in 1988 include Manila Clam, Mussels, Native Littleneck, Pacific Oyster; totaling 37,013 pounds and a value of $47,688.71 (TAbrd, 1989). Chimacum Creek is the only major fresh water drainage into Port Tc?alsend Bay. Near the town of Hadlock, Chimacum Creek divides into an east and west fork, with the west fork being moderately larger than the east fork. The west fork has a drainage basin of 21,504 acres with head waters beginning at 800 feet and is 10.7 miles long. The east fork has a drainage basin of 4,326.4 acres, is 10.4 miles long and originates at an elevaticri of 450 feet. These two taken together have a drainage of 25,830.4 acres (Richardson, 1962); the main stem of the Creek (below the east and west merger) is 2.65 miles in length. 33- - 7, �- • Port Ch Chimacum Creek AGRICULTURE Ech East Fork, Chimacum Creek RESIDENTIAL �owrlSGncd 0 2000 4000 6000 FEET t o efleZ -ow r �cp� ,o` C1.1 1 r� - �_-�,� � �� •.: ' , ' Sad - O Q v c 0 c ; HADLOCX Ech 1 h1 I Ech 2 7JE�1T ..

Station C`i2 , on the west fork, is located on the north side of Rhody Drive adjacent the Chimaczmt High School at the bridge crossing. At this station the cumulative GWZ was 322.7 with 94.4450' of the samples being greater than 100 fc /100 ml, clearly a violation of -both parts of the water quality standard. The land between CH2 and 01-13 is almost exclusively oven farm land, most of which is used for dairy cattle. Station M-33 had a cumulative G4V 101.78 with 55.56% of the samples greater than 100 fc /100 ml. This station is located in the middle of the dairy farm, below a holding yard used to detain cattle for a short period. Several meters downstream of Cci3, Nailors Creek empties into the Chimacum Creek. From this station the valley floor remains flat and has a slight increase in elevation. Station CH3.5 is located at the bridge where the creek "dog legs" under Center Valley Read and then back again to the mast side of the road. Here the cumulative aW was 155.23 with 55.5690 of the samples being greater than 100 fc /100ml. Station CH4 is located an the north side of Eaglemount Road where Chimac= Creek passes through a culvert and is immediately down creek of a large active pasture. The cumulative a- W was 94.13 with 33.33% of the samples being greater than 100 fc /100 ml. From this station the Creek turns north continuing through the pasture and a sediment catch basin. After the catch basin, the Creek begins to gain elevation more rapidly than elsev&ere in this fork of the watershed. Located above the sediment basin, on the up -creek side of the pasture lard, is station CH5. Here the cumulative G4V was 23.25 with 22.22% of the samples greater than 100 fc /1CO ml (Figure 13, Table 8). Nailor creek is a moderately low volume Creek that is a tributary to west fork of C:-limacm Creek, entering several meters below station CH3. Because much of the valley in this area consists of peat material, flows at this station were not possible because the creek bed is too mushy to stand on with out sinking. An estimated flow of 1/5 (.3 - 2.6 cfs) of the flow _ of Chimacun Creek has been used as an approximation for Nai s lor Creek. Station NA1 has a cumulative CxW of 115.87 with 43.75% of the samples being greater than 100 fc /100 ml. The Creek flows from the west, ana crosses under West Ch=c= Road, the location of station NA2. At this staticn the cumulative G1 was 19.92 with 37.5% of the samples being greater than 100 fc /100 ml (Figure 14, Table 9). The east fark of the Creek is a moderately smaller watershed, with a narrower basin floor and a smaller stream glow. Station ECHI is located east of Center Valley Road, near Hadlock. The cumulative GMV was 142.51 with 61.11% of the samples taken greater than 100 fc /100 ml. ECH2 is located an the north side of Beaver Valley Road where the Creek passes under the road. The a-W is 213.44 with 66.67% of the samples greater than 100 is /100 ml. From here the valley floor gradually widens while the Creek remaining an the eastern side of the valley.

Station E7H4, located on the north side of Egg & I Road, had a cumulative aW of 58.37 with 75% of the samples being greater than 100 fc /100 ml. Fran this station um, East C'imacum. Creek turns abruptly to the west and begins to gain elevation rapidly. Of the staticns monitored on the two forks of Chimactun Creak, CH2 clearly had the highest fecal pollution level. The CI%W at this station is over three times as -high as the GMV at station CH3. It has been observed that on the east side of the creek, about 50 meters above tile; station, numerous animals have unrestricted access to the creak. Given the number of cattle in the pasture and the magnitude of the stream bank erosion, it is difficult to assess a source other than cattle being the most significant contributor to the bacterial pollution problem at this station. The elevation from C1H3 to CH2 drops only five feet over a distance of approximately two miles. Because of this low gradient large parts of the valley are flooded at least one time annually and often several times per year. Such flooding has a historical record and may innundate whole farms and cover low sections. Even with wet season innundation, fc density was much lower than that of the dry season. This phenomenon of lower levels during the wet season is most likely a result of dilution of fecal coliform from the great quantities of water and/or because there are fewer animals kept in the pasture during winter. Animal numbers typically resume again in the summer months. Periods of innundation may be as long as a month and usually occur in the period from November to April (FuLloarson, 1955) . To this end, the local watershed residents have coordinated their own strategy to effectively deal with the water quality problems. To date, they have planned their strategy and the results appear encouraging and impressive. Out of their strategy for improving the situation in their watershed came the following elements; the sediment catch basins, controlled dredging of the Creek corridor where needed, several voluntary enhancement groups and the local high school with an on -going fish enhancement program. Port Townsend Bay has two classes of water. Class "A" water is west of a line from Point Wilson to Kala Point; the balance of the Bay is Class "AA" (Figuze 14). Station PT BR is located in the Port Tomisend Boat Haven, mid channel off the Coast Guard dock. At this station a cumulative GMV of 7.21 with 13.33% of the samples being greater than 43 fc /100 ml (Table 10). Station PTO, located approximately 75 meters off the main loading dock of the Port Townsend Paper Company, had a GMV of 7.11 with no samples greater than 43 fc /100 m1.-At the mouth of Chimacm Creek,' three quarters of a mile south of Kala Point, station PT2 had a c mlative GM of 7.09 with 26.67% of the samples being greater than 43, fc /100 ml.

'• i MATS MATS BAY%PCRT L TDLCW SYSTEM Mats Mats Bay Characteristics: Class "AA" (Extraordinary). As figure 1 shows, Mats Mats Bay and Port Ludlow are in the same drainage basin. The land use is roughly fifty percent timber, thirty percent clear cut, eight percent residential, commercial, urban and thirteen percent agriculture. For Mats Mats Bay there are two very small fresh water sources entering the bay. One of these is a small seasonal drain entering the bay at the norttu%lest shore. The second is a year around flow entering the bay at the southvge-st portion of the bay. There is very little agricultural activity in this drainage; most of it is located on the west shore of the bay. On Basalt Point, the peninsula that makes up the northeast shore of Mats Mats Bay, is a rock quarry pit that has been in operation since 1932 and average 300 tons of crushed rock per year. Most of the material loading onto barges occurs from the east side of Basalt Point, facing Puget Sound. To mitigate any potential effect of surface water run off into the bay, a fiberglass blanket screen has been installed that traps any suspended material that might enter the bay. Also on the east share, south of the rock quarry, is a herring bait operation. Floating net pens are used for holding live herring prior to packaging, with a resident time that ranges from ten to fourteen days. The facility pac'.mr,.es approximately 225,000 dozen herring per year. In 1969 the channel at the north end was dredged by the U.S. Army Corp of Engineers to facilitate the safe passage of boats during storms that used the bay as a safe haven (Hartly, 1988). On the northern shore of the bay is a small commercial shellfish operation, which has recently retired from business. FRESHWATER There are two very small fresh water sources entering the Bay. The first source is a small seasonal drain entering the bay at the northwest shore. This drain flows through a corner of a small pasture that periodically has a few horses in it. The second source is a year around flow entering the bay at the southrr&--st portion-of the Bay. There is very little agricultural activity in this drainage, most of it, however, is located on the west shore of the Bay. Entering at the northwest shore of the Bay,,Matsl had a wet season a of 39.39 and none of the samples greater than 100 fc /100 m1. on the north side of Bayview Drive, up -creek of the pasture is station Mats2 and it had wet season GN of 22.52 and none of the samples greater than 100 fc /100 ml. 47 Entering at the southwest portion of the shore there are two very small flaws. East drain had a cumulative G,1V of 38.88 and no samoles were greater than 100 fc /100 ml. To the west, west drain had a cumLlative of 44.72 and no samples were greater than 100 fc /100 ml ( Figure 17, Table 11). MARINE WATER This is the smallest of the bays monitored and the most enclosed. Over the project period there were four ambient stations monitored (Figure 16). Station Mats2, located near the mouth of a small fresh water input at the southwest end of the bay, had a cumulative G7 of 1.77 and none of the samples greater than 43 fc /100 ml. Approximately mid -way along the west shore, station Mats3 had accumulative of .44 and no samples greater than 43 fc /100 ml. At the northwest end of the bay near the seasonal stream station Mats4 had a cumulative HIV of 1.99 and none of the samples greater than 43 fc /100 ml. Station Mats5, located at the north end the bay, had cumulative GAV of .51 and no samples greater than 43 fc /100 ml (Figure 18, Table 12). At all stations the fecal coliform levels are well within state standards. Port Laci7cw Characteristics: Class "AA" (Extraordinary). Located at the head of the bay, Ludlow Creek is the primary source of fresh water into the bay. The drainage basin of this creek is 8,640 acres (Richardson, 1962) and supports a small number of Steelhead, Searun Cutthroat and limited Coho and Chun (Coccoli, 1988). The agricultural activity in this basin are located in the upper reaches of the drainage. On the north shore, at the head of the bay and adjacent the Inner Harbor, is a log dump that has an average annual production of ten to twelve million board feet of timber per year,'with fourty to sixty truck loads of logs a day during peak season. North of the log dump is a 283 slip boat harbor with seven live- aboards. Both the Inner Harbor and the Port Ludlow Marina receive heavy visitor usage during the sumner boating season. The area of Ludlow Bay south of a line from Tala Point to the west shore is classified as prohibited, as is required of waters in the vicinity of a sewage out -fall and /or in the proximity of marinas. FRESHWATER Ludlow Creek drains an area of 8,640 acres with the head waters originating at approximately 375 feet and is about 5.54 - miles °in length. Ludlow creek is the only major fresh water flow into Ludlow Bay and empties into it at the head of the Bay (Figure 19). Station Ludlowl, located at the mouth cf. the Creek which is tidaly inundated during high tide, had a cumulative GW of 20.15 and none cf the samples were greater than -100 fc /100 ml (Table 13). The Creek flows from westerly_ direction,. MATS MATS WARRY AQ i ,S 80 70 cu 0 50 0 s j 30 W W W 30 W J W 20 10 C F A M J A N MONTH (1988) MA751 WESiCR EASTCR ® MAT-Z2 Figure 1 ?.

Station Ludlcw2 is located immediate up Creek of the culverts and had cumulative G�N of 26.56 and none of the samples greater than 100 fc /100 ml. Where the Creek gasses under Embody F)ad, station Ludlow3 had accumulative G`QV of 37.72 and 25% of the samples greater than 100 fc /100 ml. The Creek continues to parallel Beaver Valley Road and makes a right angle turn to the east where it again passes under Beaver Valley Rd and parallels Swansonvill Road. At the crossing, - station Ludlow4 had a cumulative GMV of 28.16 and 20.00% of the samples greater than 100 fc /100 ml (Figure 20, Table 13). As mentioned above, agricultural activity exist only in the upper reaches of the creek; stations Ludlcw2 and above. Like other creeks, Ludlow Creek shows signs of fc seasonality. Unlike other stations, this creek has elevated levels at the head water stations with decreased levels at the mouth of the creek. These lower levels are probably a result of two situations: the first, is the absence of agriculture or residential along the last 1.5 miles of the creek corridor; the second is die -off of fecal coliform as they flow down creek. MARIM WATER Ludlow Bay had five ambient stations that were monitored through the project period (Figure 20). Inside the boat harbor on the north shore station LD1 had a cumulative G`flV of 1.85 and none of the samples greater than 43 fc /100 m1. Several meters off the north end of the log raft, station LD2 had a cumulative GIN of 3.99 and 7.96% of the samples greater than 43 fc /100 ml. To the south, behind the Twin Islands in Inner Harbor, station LD4 had a cumulative G'Ylil of 1.11 and no samples were greater than 100 fc /100 ml. Approximately 5 metersoff the dock on the south shore, station LD5 bad cumulative GW of 1.15 and none of the samples greater than 100 fc /100 ml (Figure 22, Table 14). During the July 4th weekend, samples were collected at several locations and aralyzed using M-Tec method (appendix B) . This particular period was chosen because of the high number of recreational boaters that use this area during the boating season. sampling occurred on the last day after a large influx of recreational boats into the bay. As the results from appendix B show, most ambient stations had elevated fecal coliform levels during the period of heavy boater use. The day prior to sampling 24 boats had over- nighted in the Inner Harbor and by 10:00am the next morning when sampling began only 10 were remaining. Faust (1982) found that Fc bacteria in shallow bays increased from 3 to 28 fc /100 ml soon after the arrival of recreational boats, persisted during the weekend (Labor Day), and decreased soon after the boats departed. Patmont et.al.(1985) conducted a study in Ludlow Bay and found that the fecal coliform levels:-in.both'water and shellfish appeared to increase , substantially with boating activity over the 8-day study period during the 4th of July weekend. The marine water quality is well within the state standard, as is the fresh water from Ludlow Creek. The marina had the most consistent and highest levels of fecal coliforms. Water quality appears to fall during periods when there is heavy boating activity over a few day period. 54 LAND USE - RESIDENTIAL r AGRICULTURE �y o 2000 4000 FEET � �m A ''vtelC.

Sunmlary of monthly fecal coliform GW's for Port. Ludlow. (LD = Port Ludlow) 53 . A. 53 JAN CAVE SYST- 1 Jackson Cove: Class "AA" (Extraordinary) . There are two relatively small fresh water sources: Spencer Creek located at the northeast portion and Jackson Creek on the west shore. A community owned commercial shellfish growing area extends from Maple Creek north to Plana Point. The land use is approximately seventy percent timber, twenty five percent clearcut, and five percent urban. There are two relatively small fresh water sources: Spencer Creek located at the north-east portion and Jackson Creek on the west shore. There were four ambient stations monitored in Jackson Cove (Figure 23). Station Jacl located approximately 40 meters off the Spencer. Creek mouth of the west shore had a cumulative GMV of .79 and none of the samples were greater than 43 fc /100 ml. At the northwest shore where Jackson Creek empties into the cove, station Jac2 had cumulative GW of .43 and none of the samples were greater than 43 fc /100 ml. Station Jac3 located aproximatly 25 meters off the dock and had cumulative GNIV of .77 with none of the samples greater than 43 fc /100 ml. Station Jac4, off the pier on the north end of the cove had a cumulative G W of .23 and no samples were greater than 43 fc /100 ml (Figure 24, Table 15). The water cniality in this cove is excellent and had the lowest levels of bacteria or" all the bay's monitored. warA PT. Figure 23.

Summary of monthly fecal coliform OT's for Jackson Cove. (jAC = Jackson Cove) 61 Fecal Coliform Lcadding Flows were taken at the mouth of creeks and their significant tributaries. These flows taken together with the bacterial concentration levels provide a means of making a guantitive comparison between streams. Loading estimates from the watershed were Used on individual creek loadings into the marine water. In cases when data were absent no modeling was conducted to fill in the missing data. Using this method likely underestimates the actual loadings into the bays. Flows were not conducted for the fresh water sources into Mats Mats Bay or Jackson Cove; and likewise loadings are not represented. DISCOVERY RAY SYSTEM Discovery Bay watersheds had a total loading budget of 300,000 billion (301144.85) fecal coliforms. Common to most drainage were increases in the loading levels during the summer /dry months. Snow Creek represented 55% of the loading budget followed by Salmon Creek with 42%, Zerr Drain 2.38% and Contractors Creek .32 %. During periods when cattle were in and around Houck Creek, elevated levels of fecal coliform were recorded; these same periods (February, March, June, July) also had the highest loadings from the Creek (Figure 25). Fresh water sources are most likely responsible for the periodic elevated levels at the marine station at the hears of the bay. PORT TUAMEE ID BAY SYSTEM Port Tovaisend Bay had a total loading budget from Chimacum Creek of 89.32 billion. Because this is the only fresh water input into the bay, it represents 100% of the loading. On the other hand, as figure 26 illustrates, the west fork of Chimacum Creek contributed significantly to the loading when compared to either Nailors Creek or the east fork of Chimac;um Creek. Nailors Creek contributed only 4.6% of the fecal pollution into the west fork. The loading of the west -fork was nearly 8 times greater than the loading of the east fork. In numerous places along the creek, serious bank erosion has resulted from cattle accessing the water. This has led to elevated levels and is the probable cause of the elevated levels at station PT2. LUDLCW BAY This creek is the only major fresh water source into the bay. Because most of the _loading` data is representative 'ofthe dry season, it, is not possible to estimate the annual loading into the bay.-The loading into this bay from Ludlow Creek was 11.16 billion fecal coliform (Figure 27). There does not appear to be elevated levels at marine stations in response to the loading fram the creek. 62 160 150 140 120 120 110 Z 100 O 90 m 80 0 a 70 O J O 60 5C 4C 3C 2( V F A M J i A s CT 1988 = SA A10FffH® SN 189$® ZERR Figure 25.

Monthly fecal coliform loading into Port Ludlow from Ludlow Creek. Under ambient conditions there were varying degrees of bacteriological impacts. Isolated problems do exist and their correction anti /or the prevention of future impacts or the closure of commercial shellfish harvesting areas will require the cooperation of the land owners, local government, state agencies and the Tribes. FRESHWATER Headwater stations, above development, generally had much lower levels of fecal coliform than reaches with residential or agricultural development along the corridor. Consistent violations of the Washington State Water Quality Standard existed in Salmon Creek, Houck Creek, Snow Creek, Andrews Creek, Zerr Drain, Chimacum Creek (both east and west fork) and Nailors Creek. Associated with creeks that had extremely high pollution levels in lower reaches were agricultural practices, particularly in areas where domestic animals had direct access to the water. in reaches where domestic animals had access to the creek /streams bank erosion occurred, manure was found in the water and both fecal coliform concentrations and loadings from the creek increased markedly. MAR= WATT Stations located at the head of the bays had slightly elevated bacterial levels of pollution than stations located further from the head of the bay. Periodically, extremely elevated levels occurred near the fresh water sources in Discovery Bay and Port Townsend Bay. These elevated levels are most likely due to poor animal keeping Practices in and around fresh water sources that feed the bays. Recent flooding in the Discovery Bay watershed may be related to the logging which has occurred in the post logging years of Salmon and Snow Creeks. Flooding of pastures and poor animal keeping practices can lead to increased levels of coliform pollution in the water and as a result threatens commerical shellfish harvesting at the head of the Discovery Bay. Port Townsend Bay had periodic elevated levels at the boat haven and near the mouth of Chimacum Creek. Port Ludlow Bay experienced an increase in fecal coliform in July at the end of heavy recreational boat use. Jackson Cove had the lowest levels of fecal coliform of all the bays monitored, the water quality is excelent. The relationship between land use and bacterial pollution can be difficult to determine at times. :Streams provide a constant supply of water to larger downstream rivers, lakes and marine estuaries and water quality impacts are often evident far from the source of the pollution. in some cases, however, the cause of the pollution is more straight forward. For example, stream reaches that flowed through agricultural area where animals had access the water was heavily impacted and water quality suffered. Aminals in and around the stream trampled streamside vegitation, damaged stream banks, contributed to erosion, streambed .. sedimentation, bacterica pollution frcm manure and impairment of an.aziranous fish spawing and rearing habitat. Generally, agricultural nor=int pollution can be controlled at acceptable levels by the use of BtvF l s . BZ 2's are proven water pollution abatment tools developed through research and field experience (Wallace, 1987). 67 1 Broadherst, Ginny. 1988.

Rippey et a-. (1987) found mTEC recovery to a mean of 925o of the recovery of MPN procedure. Determan (et a1., 1985) found the correlation in their work with the two methods to be highly significant. The following ea_ization was used to estimate the FC (MPN) values from FC (MF) results obtained in their study: log10 FC(MFN) = 0.95 log10 Imo' + 0.23 This same equation was used for the correlation to estimate the FC values from MF method to MFN values. 71 APPENDIX C The attached data are fran the bay's and freslr,ater sources monitored.
