-Water Quality-
Lake Health
Eagle Lake has been monitored for decades by volunteers, the DNR and several contracted sampling projects. In the 1990's, volunteers began monitoring water clarity with a black and white Secchi disk for readings. Volunteers are the source of the majority of Wisconsin's lake water quality data, and their dedication is greatly appreciated.
​
In 2016, the DNR added Eagle Lake to the Impaired Waters list for the State of Wisconsin. This is mainly due to very high nutrient levels and poor quality of run-off the lake receives from the agricultural watershed.
​
In 2018, the ELMD resumed annual water quality data with help from DNR surface water grants and the CLMN program (Citizens Lake Monitoring Network). Now, water clarity is again being documented on a routine schedule. In addition, Phosphorus & Chlorophyll samples have been added to collection efforts.

Reports and graphs featuring data collected by volunteers, DNR staff and others can be viewed below.
