2.2.1 Topography and Drainage

The Dutch Lake subwatershed is located within the Lonsdale-Lerdal till region, and the topography is typical of that region ? hummucky, rolling and hilly, with some steep slopes on hillsides and along the southwestern shore of Dutch Lake and adjacent wetland.  The 2003 MCWD Hydrologic, Hydraulic, and Pollutant Loading Study (HHPLS) subdivided the Dutch Lake subwatershed into seven subwatershed units, designated DL-1 through DL-7 (see Figure 2).  The upper portion of the subwatershed drains to a large wetland complex in the central subwatershed, which in turn drains south and then east to Dutch Lake.  Dutch Lake outlets via Dutch Lake Creek east to Jennings Bay of Lake Minnetonka.
