ABOUT LONE LAKE
Lone Lake, just off Shady Oak Road in Minnetonka, is a deep lake with great water quality and many recreational opportunities.
Water quality of Lone Lake is good, with average nutrient levels better than state standards. Phosphorous is the nutrient that fuels algae and plant growth. Phosphorous loading has caused some blue-green algae blooms, but algal toxins were below public health advisory levels. Latest aquatic plant surveys have shown Lone Lake is barely meeting DNR standards for plant diversity with 12 total plant species. Overall, Lone lake is a healthy, shallow lake with no water impairments listed.

To improve the health of Lone Lake, the Nine Mile Creek Watershed District installed a raingarden in the center and around the edges of the lower parking lot.
The raingardens installed at Lone Lake Park significantly reduce the amount of phosphorus and other pollutants from getting into Lone Lake. Prior to the raingarden installation, over half of the phosphorus entering Lone Lake came from stormwater running off streets and parking lots around the lake.
Raingardens also provide food and shelter for pollinators, like butterflies. The Lone Lake Park project was completed as part of the Minnetonka Lakes Water Quality Improvement Project.
