3.1 Water Quality
- Many of the bays of Lake Minnetonka
are near or better than their water quality goal, but three bays in
particular have significant water quality problems: Halsteds
Bay, and Stubbs Bay.
West Arm and Priest Bay
also do not meet their goal and are influenced by the water quality in the
- A whole lake model is necessary to
fully understand the complex mixing that occurs within the lake and
between the bays and to better forecast water quality.
- No or limited data is available for smaller
lakes in the subwatershed, including Peavey, Marion,
Louise, Shavers, Forest, Galpin, and Lost Lake.
- Classen Creek conveys a significant
phosphorus and sediment load to Stubbs
- Development, redevelopment, and
reconstruction in the subwatershed are predicted to increase nutrient and
TSS loads from the watershed as well as increasing the volume of
stormwater runoff, potentially further degrading water quality downstream.
