In 24K NHD a single water body polygon, surrounds the Glesne & Bloomyhre lakesbut all other sources (DRG, GNIS, PWI)suggest that it should be two lakes.

McKeown Lake is represented by three polygons. The dataoriginated from MnDNR 24K lake data which is based on NWI open water polygons. We will revisit what is the best representation for these lakes. How does it impact lake area and flow?
