Notes
Big Stone Lake was originally included on the 303(d) list in 1998 due to mercury concentrations in fish tissue. This water was assessed for the 2012 listing cycle and the original listing due to mercury levels in fish tissue was confirmed.
Big Stone Lake was evaluated for phosphorus and algae every two years between 2014 and 2024. Phosphorus levels were found to be too high, however algae blooms do not appear to be an issue. Aquatic plant communities were also in good condition. Big Stone Lake is on the Impaired Waters List.Pollutant
