Notes
Prairie Lake was evaluated for phosphorus and algae every two years between 2014 and 2018. Phosphorus levels were found to be too high, which was reflected in algal blooms. This lake is covered by a restoration plan: A Water Quality Strategy for the Land and Waters of the Red Cedar River Basin (expires 2026).Pollutant

Impaired Water Notes
All 5 lakes were documented as having hypereutrophic total phosphorus levels in 1996. Sediments and nutrients which may drive algae blooms to the point of being dominated by blue-greens which have the potential to produce toxins as well as suppress D.O. levels.
Nonpoint source runoff from agricultural sources.
Tributary and lake monitoring was conducted in 1996 and compiled in a Barr Engineering report in May 1999.
