Wetland name or number 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 two years NOTE: The riverine unit can contain depressions that are filled with water when the river is not flooding. ❑NO -go to 6 ®YES—The wetland class is Riverine 6. Is the entire wetland unit in a topographic depression in which water ponds, or is saturated to the surface, at some time during the year. This means that any outlet, if present, is higher than the interior of the wetland NO—go to 7 ❑YES—The wetland class is Depressional 7. Is the entire wetland unit located in a very flat area with no obvious depression and no overbank 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 your wetland.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 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 HGM Class to Use in Rating Slope+Riverine Riverine Slope+Depressional Depressional Slope+Lake-fringe Lake-fringe Depressional+Riverine along stream within boundary Depressional Depressional+Lake-fringe Depressional Salt Water Tidal Fringe and any other class of freshwater wetland Treat as ESTUARINE under wetlands with special characteristics If you are unable still to determine which of the above criteria apply to your wetland, or you have more than 2 HGM classes within a wetland boundary,classify the wetland as Depressional for the rating.
