A comprehensive evaluation of Silver Lake is now complete. The evaluation was conducted by scientists from the U.S. Geological Survey (USGS) and Grand Valley State University (GVSU). As part of the evaluation, water quality conditions in Silver Lake were thoroughly examined and major water and nutrient inputs to the lake were measured. The evaluation included two years of intensive field sampling, followed by one year of data interpretation and a final report of findings. The results of the evaluation can be used to guide future decision-making regarding the management and health of Silver Lake.
With respect to the long-term health of Silver Lake, septic systems were found to be the largest controllable source of nutrient input to Silver Lake; installation of a sewer system would reduce the frequency and intensity of algal blooms in Silver Lake.
