As part of the Michigan Cooperative Lakes Monitoring Program (CLMP), the CLWA sponsors comprehensive scientific testing of Crystal Lake’s water. Monitoring provides advance warning, so that early action can be taken to protect Crystal Lake.

CLWA’s testing through the CLMP focuses on the Lake’s trophic status, measuring clarity, Chlorophyll-a, and Phosphorus. The latest results are consistent with past years and show no significant problems. The full data report is available HERE.

In addition, the CLWA carries out its own intensive program of monitoring additional aspects of water quality. These include aquatic plants and invasive species, bacteria, shoreline condition, dissolved oxygen and temperature.

The CLWA and its predecessor organizations have monitored the chemistry of the Lake’s water for more than 50 years. All this information is now gathered in an interactive database that allows us and future generations to easily access lake health data and track trends that may identify potential problems – before they become major problems later on. To learn more about the database and what it is doing for us, watch this VIDEO prepared by CLWA Lake Biologist John Ransom.
