Muskegon Lake Improving
Phosphorus and chlorophyll concentrations in Muskegon Lake, Michigan have been cut in half since 1972. Phosphorus concentrations in the lake dropped by 65 percent between 1972 and 2006; chlorophyll concentrations were down 75 percent; and average water clarity rose from 5 feet to 7.5 feet. Scientists at Grand Valley State University conducted the study. Improvements in treatment of wastewater in the watershed have had a dramatic impact in cleaning the lake.
