Created through the Cooperative Lakes Monitoring Program, the 2022 Data Report for Gratiot Lake is now available. Volunteers at Gratiot have participated for 22 years in collecting data on water transparency and phosphorus levels. These parameters help to track what changes or trends may be occurring in the health of the Gratiot Lake ecosystem and also can point to human caused pollution that may be impacting lake quality (like fertilizer use on lakeside lawns or practices that allow lots of sediment to runoff into the water (extensive heavy logging or roadbuilding or clearing land for construction for instance).
