Two Douglas County Lakes at Risk

Phsophorus Pollution

Two Douglas County Lakes are at risk from an Ottertail County Lake. High levels of phosphorus could impact Lake Ida and Miltona. The Douglas County board is taking measures to drain already infected lakes into alternative areas instead of drainage ditches leading to other lakes. They will be taking studies to find alternatives to help deal with the flooding of Nelson Lake.

Too much phosphorus can cause increased growth of algae and large aquatic plants, which can result in decreased levels of dissolved oxygen– a process called eutrophication. High levels of phosphorus can also lead to algae blooms that produce algal toxins which can be harmful to human and animal health.
