If the hydrologic criteria listed in each question do not apply to the entire unit being rated, you probably have a unit with multiple HGM classes. in this case, identify which hydrologic criteria in questions 1-7 apply, and go to Question 8. 1. Are the water levels in the entire unit usually controlled by tides except during floods? NO - go to 2 YDS the -wetland -clafis i&TIA-1 Fringegam? 1.1 is the salinity of the water during periods of annual low flow below 0.5 ppt (parts per thousand)? NO - Saltwater Tidal Fringe (Estuarine) YES - Freshwater Tidal Fringe If your wetland can be classified as Freshwater Tidal Fringe use the forms for RiverInewetlanda If it is8altwater Tidal Fringe it isan Estuar inewetiand and is not scored. This method cannot be used to score functions for estuarine wetlands. 2. The entire wetland unit is flat and precipitation Is the only source (>90%) of water to it. Groundwater and surface water runoff are NOT sources of water to the unit. NO-goto3 If your wetland can be classified as Flats wetland, use the form for Depressional wetlands. 3. Does the entire wetland unit meet all of the following criteria? _The vegetated part of the wetland is on the shores of a body of permanent open water (without any plants on the surface at any time of the year) at least 20 ac (8 ha) in size; _.At least 30% of the open water area is deeper than 6.6 ft (2 m). NO - go to 4 Vks 'WV ,.,nr R,,.3 . i, :k0--IL1441g 4. Does the entire wetland unit meet all of the following criteria? __.LThe wetland is on a slope (slopecan be very gradual), _The water flows through the wetland In one direction (unidirectional) and usually comes from seeps. It may flow subsurface, as sheetflow, or in a swale without distinct banks, _The water leaves the wetland without being impounded. NO - go to 5 = L T•=�tr�t1;arss ipe NOTE: Surface water does not pond in these type of wetlands except occasionally in very small and shallow depressions or behind hummocks (depressions are usually <3 ft diameter and less than 1 ft deep). 5. Does the entire wetland unit meet all of the following criteria? _The unit is in a valley, or stream channel, where it gets inundated by overbank flooding from that stream or river, _The overbank flooding occurs at least once every 2 years.

This means that any outlet, if present, is higher than the interior of thewetland. YES - The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbatik flooding? The unit does not pond surface water more than a few Inches. The unit seems to be maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural outlet. NO - go to 8 YES - The wetland class is Depressional 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small stream within a Depressional wetland has a zone of flooding along Its sides. GO BACK AND IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the appropriate class to use for the rating system if you have several HGM classes present within the wetland unit being scored. NOTE: Use this table only if the class that is recommended in the second column represents 10% or more of the total area of the wetland unit being rated. If the area of the HGM class listed In column 2 is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the total area. HGM classes within the wetland unit being rated Slope + Riverine HGM class to use in rating Riverine Slope + Depressional Depressional Slope + Lake Fringe lake Fringe Depressional + Riverine along stream within boundary of depression Depressional Depressional + Lake Fringe Depressional Riverine + Lake Fringe Riverine Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE If you arestill unabletodeterminewhich of theabove criteria apply to your wetland, or if you have more than 2 HGM classes within a wetland boundary, classify thewetiand as Depresdonal for the rating.
