Eagle Lake is located in Kandiyohi County. It has a surface area of 845 acres. The total watershed is about 12,920 acres including Eagle Lake. Land use in the watershed is characterized primarily by water and marsh (24 percent), pasture (30 percent), and cultivated (34 percent) uses. These percentages are typical for lake watersheds in this region of the state - North Central Hardwood Forests ecoregion. Eagle Lake was sampled during the summer of 1994 by the Minnesota Pollution Control Agency (MPCA) staff and citizens from the Eagle Lake Association (Association). Water quality data collected during the study reveal summer-mean total phosphorus (TP) concentration of 43 pg/L, mean chlorophyll a of 21 pg/L and Secchi transparency of 4.3 feet. The phosphorus and chlorophyll a for Eagle Lake are within the range of values exhibited by reference lakes in this ecoregion, while the Secchi value is lower than what would be exhibited by reference lakes in this ecoregion. Total phosphorus, chlorophyll a and Secchi transparency help to characterize the trophic status of a lake. These measures indicate eutrophic conditions for Eagle Lake.
