1.0 Introduction and Summary
The Dutch Lake subwatershed is located along the western boundary of the Minnehaha Creek Watershed District (MCWD or District) and within the cities of Minnetrista and Mound. The subwatershed includes Dutch Lake, Dutch Creek, large areas of undisturbed or low-density development, and numerous wetlands. The upper watershed is drained by a series of wetlands connected by channels and culverts to Dutch Lake. Dutch Lake outlets by Dutch Creek, which flows about 0.8 miles to Jennings Bay of Lake Minnetonka.
Dutch Lake does not meet its water quality goals. Dutch Creek conveys high phosphorus and sediment loads to Jennings Bay. The sport fishery in Dutch Lake is good. No ecological data is available for Dutch Creek. Numerous high-value wetlands are present in the subwatershed. The western subwatershed includes wetland and upland of high ecological value, including maple-basswood forest and tamarack forest.
Over the next ten years, the District’s focus in the Dutch Lake subwatershed will be on conserving ecological integrity within the subwatershed, protecting the high-value wetlands, and improving water quality in Dutch Lake. The following will be particular focus areas:
- Conserving ecological integrity through Land Conservation Program activities in key conservation areas.
- Improving water quality in Dutch Lake through internal load management and other projects.
- Minimizing impacts on water resources from future development through enhanced regulation that requires higher levels of pollutant removal and increased infiltration of runoff.
- Working cooperatively with the DNR, Three Rivers Park District, Hennepin County, private landowners, and other partners to create a conservation corridor that connects high-value resources with Gale Woods and Baker Regional Park Reserves and Lake Minnetonka.
