Diamond Lake is located in Dayton, MN

The purpose of our organization is:

• To support and conduct non-partisan research, education, and informational activities to increase public awareness of the Diamond Lake

• To improve the lake quality and habitat

• To prevent lake quality deterioration

Our main project for this year is treatment of the curly-leaf pondweed invasive species.  We have conducted a whole-lake treatment of invasive curly-leaf pondweed for the fourth year.  Here is our Facebook page.

We would like to thank The City of Dayton and MN DNR that are helping provide funding for the successful treatment of Diamond Lake.
