Wetland name or number A <br />5. Does the entire wetland unit meet all of the following criteria? <br />The unit is in a valley, or stream channel, where it gets inundated by overbank <br />flooding from that stream or river <br />_ The overbank flooding occurs at least once every two years. <br />NOTE.• The riverine unit can contain depressions that are filled with water when the river is <br />not flooding. <br />F./—]NO - go to 6 F_JYhS — The wetland class is Riverine <br />6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the <br />surface, at some time during the year. This means that any outlet, iifpresent, is higher than the <br />interior 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 <br />natural outlet. <br />ONO — 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 />clases. 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 <br />IDENTIFY WHICH OF THE HYDROLOGIC REGIMES DESCRIBED IN QUESTIONS 1-7 <br />APPLY TO DIFFERENT AREAS IN THE UNIT (make a rough sketch to help you decide). Use <br />the following table to identify the appropriate class to use for the rating system if you have several <br />HGM classes present within your wetland. NOTE: Use this table only if the class that is <br />recommended in the second column represents 10% or more of the total area of the wetland unit <br />being rated. If the area of the class listed in column 2 is less than 10% of the unit; classify the <br />wetland using the class that represents more than 90% of the total area. <br />a <br />�CfM Masses tvFthrn the wetlanrcluntt bezrl rate__ m <br />` ` <br />=,i`IC,rMClass�"fo U,se yn �attr <br />Slope + Riverine <br />Riverine <br />Slope + Depressional <br />Depressional <br />Slope + Lake-frine <br />Lake -fringe <br />Depressional + Riverine along stream within boundary <br />Depressional <br />De ressional+Lake-frin e <br />Depress I <br />Salt Water Tidal Fringe and any other class of freshwater <br />wetland <br />Treat as ESTUARINE under <br />wetlands with special ❑ <br />characteristics <br />If you are unable still to determine which of the above criteria apply to your wetland, or if you <br />have more than 2 HGM classes within a wetland boundary, classify the wetland as Depressional <br />for the rating. <br />Wetland Rating Form— western Washington 4 August2004 <br />version 2 Updated with new WDFW definitions Oct. 2008 <br />
