Lake Monitoring & Assessment


Image of waterfowl in a lakeMCES monitors lakes in the Twin Cities Metropolitan Area to provide a comprehensive database that allows cities, counties, and watershed management organizations to better manage and protect these lakes. MCES has monitored Metropolitan Area lakes since 1980, and an even larger network of lakes is monitored with extensive volunteer help, via the MCES volunteer Citizen-Assisted Monitoring Program (CAMP).
