EVALUATING WATER CHEMISTRY IN LAKE SARAH, MURRAY COUNTY, MINNESOTA
Minnesota lakes are vital natural resources providing wildlife habitat and influencing the quality of life and the economy. Lake Sarah, in SW Minnesota, has provided a productive walleye fishery for many years and has recently been invaded by zebra mussels. In addition, water quality has been damaged due to lawn, fertilizer, pesticide, and pet waste runoff. This study measured changes in multiple water quality parameters at two sites during summer 2020 including temperature, dissolved oxygen, conductivity, pH, ammonium, nitrate, phosphate, and turbidity. The results show there was no significant difference between the parameters at each site or between the two sites over time. Common values for the parameter averages include; temperature 21?C, dissolved oxygen 11.2mg/L, conductivity 0.499uS, pH 7.7, ammonium 0.4mg/L, nitrate 0.1mg/L, phosphate 0.1mg/L, and turbidity 74cm. All the parameters averages were below the permissive standards. Lake Sarah continues to have acceptable water quality
