Wetland name or number Wetland A <br /> NO - go to 6 YES- The wetland class is Riverine <br /> NOTE: The Riverine unit can contain depressions that are filled with water when the river is not <br /> flooding <br /> 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the <br /> surface, at sometime during the year? This means that any outlet, if present, is higher than the interior <br /> of the wetland. <br /> NO - go to 7 YES - The wetland class is Depressional <br /> 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank <br /> flooding? The unit does not pond surface water more than a few inches. The unit seems to be <br /> maintained by high groundwater in the area. The wetland may be ditched, but has no obvious natural <br /> outlet. <br /> NO - go to 8 YES -The wetland class is Depressional <br /> 8. Your wetland unit seems to be difficult to classify and probably contains several different HGM <br /> classes. For example, seeps at the base of a slope may grade into a riverine floodplain, or a small <br /> stream within a Depressional wetland has a zone of flooding along its sides. GO BACK AND IDENTIFY <br /> WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 APPLY TO DIFFERENT <br /> AREAS IN THE UNIT (make a rough sketch to help you decide). Use the following table to identify the <br /> appropriate class to use for the rating system if you have several HGM classes present within the <br /> wetland unit being scored. <br /> NOTE: Use this table only if the class that is recommended in the second column represents 10% or <br /> more of the total area of the wetland unit being rated. If the area of the HGM class listed in column 2 <br /> is less than 10% of the unit; classify the wetland using the class that represents more than 90% of the <br /> total area. <br /> HGM classes within the wetland unit HGM class to <br /> being rated use in rating <br /> Slope + Riverine 0 Riverine <br /> Slope + Depressional 0 Depressional <br /> Slope + Lake Fringe 0 Lake Fringe <br /> Depressional + Riverine along stream 0 Depressional <br /> within boundary of depression <br /> Depressional + Lake Fringe 0 Depressional <br /> Riverine + Lake Fringe Q Riverine <br /> Salt Water Tidal Fringe and any other Treat as <br /> class of freshwater wetland ESTUARINE <br /> Ifyou are still unable to determine which of the above criteria apply to your wetland, or ifyou have <br /> more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional for the <br /> rating. <br /> Wetland Rating System for Western WA: 2014 Update 4 <br /> Rating Form-Effective January 1,2015 <br />
