There is a culvert outside the wetland upslope to the east that discharges hydrology. Overall, the resource was delineated based on a lack of wetland hydrology forming a gradual boundary in most areas. Upland vegetation communities are generally dominated by boxelder, European buckthorn and Kentucky blue grass (Poa pratensis). ATYPICAL/PROBLEMATIC CONDITIONS Analysis of antecedent precipitation revealed that the area was well above average at the time of the field investigation, surface hydrology was observed in several areas. CONSISTENCY WITH DESKTOP REVIEW NWI inventoried areas were found to be generally correct but did not identify the ditched Type 1 portion. 1 Appendix B contains wetland determination data forms supporting this investigated resource: Wet Point(s): 1A Up Point(s): 1B 2 Appendix E contains MnRAM output 267
