The conveyance discharges hydrology to the Type 3 basin (dominated by <br />hybrid cattail) and adjacent Long Lake Creek. Overland flows from the northern catchment is received by a Type 2 basin <br />generally dominated by lake sedge and reed canary grass. A low-lying area resembling a flow path was investigated at 1B <br />and was determined to not be wetland. Overall, the resource was delineated based on a lack of hydric soil profile, lack of <br />wetland hydrology forming an abrupt boundary in most areas. Upland vegetation communities are generally dominated by <br />maple and basswood forest; however, the understory of most areas is densely vegetated with European buckthorn. <br />ATYPICAL/PROBLEMATIC CONDITIONS <br />Analysis of antecedent precipitation revealed that the area was in deluge at the time of the field investigation, however, <br />surface hydrology was not observed in most areas. This is consistent with the time of year and preceding months’ drought <br />condition. The soil profile investigated at 1A exceeded depths accessible by the soil probe and was therefore assumed <br />hydric based on the mapped soil unit, landscape position, and the presence of other wetland criteria. The investigated soil <br />profile at 1B revealed a restrictive layer, but the profile was determined non-hydric based on an absence of a hydrophytic <br />plant community. <br />CONSISTENCY WITH DESKTOP REVIEW NWI inventoried areas were found to be generally correct; however, additional wetland was found in hydric soil units. <br /> 1 Appendix B contains wetland determination data forms supporting this investigated resource: Wet Point(s): 1A, 1C <br />Up Point(s): 1B, 1D, 1E <br />2 Appendix E contains MnRAM output <br /> <br />
