Of COMMUNITY DEVELOPMENT Jefferson County Department of Community Development 621 Sheridan ATTENTION: Michelle Farfan, Assistant Planner Port Townsend, Washington 98368 Dear Ms Farfan: SUBJECT: Request for Stream Type Verification, Jacobsen Land Partnership, Irondale Acre Tracts, Unnamed Tributary to Admiralty Inlet, Section 12 and 13, Township 29 North, Range 01 West, Section 7 and 18, Township 29 North, Range 01 East, Jefferson County During two days of field review of the above referenced stream system channel gradient and width were used to determine stream type and potential fish utilization. Local information indicates that this stream flows year round, The stream channel is steep in the reach between the two road right of ways on the Irondale Tracts and moderates upstream of the upper road right of way, Substrate in the channel alternated from fine silt to course gravel, with many suitable spawning areas, A portion of the channel flows through an associated forested wetland reach in the lower gradient area downstream of the lower right of way on the lrondale Tracts and upstream of the ponds, It is difficult to exactly place these streams on the map of the lrondale Tracks because the maps do not show section lines, local roads or compass direction, Heading south on the lrondale Tracts road right of way furthest upstream I noted two stream crossings, One drains a sedge wetland a couple hundred feet upstream of the road right of way. There were tvv'O exit channels from this wetland, one flowing independently under the road right of way and another entering the main stream channel upstream of the road right of way further to the south. This first stream channel that I noted on the road right of way maybe the west fork of the system that the map show originating at the south line of Section 13 and flowing for a mile until its confluence with the main stream channel. This main stream channel is larger, further to the south and drains a basin that according to the map that extends 3/4 of a mile to the south along the east line of Section 13, and has two tributaries feeding into it from Section 18, I only examined these streams from the upper road right of way on the Irondale Tracts downstream past the lower road right of way on the lrondale Tracts, and ended my survey at the county road. LOG ITEM # ~(p e e , 11 Ms Farfan July 5, 2000 Page 2 Appro.ximately midway between the two. road right o.f ways an the lrondale Tracts the stream changes fro.m a Type 4 to. a Type 3, At the lo.catio.n where the lo.wer ro.ad right o.fway meets the stream channel there is a tributary an the right bank facing do.wnstream, This tributary has abo.ut 900 to. 1000 feet o.f Type 3 habitat and appears to. also. be lo.cated an the lrondale Tracts, At the co.unty ro.ad there is a undersized and perched co.ncrete culvert that is a barrier to. upstream fish passage, Plank weirs have been installed by lo.cal members o.f the co.mmunity to. impro.ve fish passage and provide additio.nal po.o.led rearing area far co.ho. salman. With the installatio.n o.fthe plank weirs same adult co.ho. salman can pass the co.ncrete culvert and spawn in the stream channel abo.ve, Further upstream passage to. the area o.f the Iro.ndale Tracts is precluded by the existence o.f two. artificial po.nds, These po.nds are co.nstructed so. that the entire stream flaw is ro.utedthrough them with aut any provisio.n far upstream fish passage. In the absence o.f this human caused barrier to. adult fish passage I wo.uld expect adult salman spawning into. the area o.f the Iro.ndale Tracts. During fish passage surveys in 1999 trout were no.ted in this reacho.f the stream that resulted fro.m trout that were planted in the po.nds, I did no.t no.te the presence o.f these tro.ut the day I surveyed this stream reach. In co.nclusio.n I determined that a po.rtio.n o.f each fo.rk o.fthis stream system extending o.nto. the Iro.ndale Tracts is a Type 3 fish bearing stream. That the Type 4 reaches and headwater wetlands abo.ve are co.ntributing year ro.und stream flaw do.wnstream into. the Type 3 reaches. With the remo.val o.r mo.dificatio.n o.f the human caused barriers to. adult fish passage this po.rtio.n o.f the stream system co.uld be a pro.ductive salman habitat. We reco.mmend that the Type 3, Type 4 and headwater wetland areas o.fthis stream system receive riparian buffers adequate to. pro.vide far summer stream flaws, shade, large wo.o.dy debris, and litter. Future wo.rk to. upgrade these ro.ad right o.fways will require Hydraulic Pro.ject Appro.vals (HPAs) far the stream cro.ssings and will require drainage plans to. pro.tect the stream channels and water quality fro.m sto.rm water run o.ff and ero.sio.n. e e t ,. ". Ms Farfan July 5, 2000 Page 3 Is possible that the year round flow in the stream reaches upstream of the upper right of way on the Irondale Tracts could support resident trout populations. Further field work would be required to determine if this is the case. Thank you for the opportunity to provide this information.
