The Minnesota Pollution Control Agency's (MPCA) Citizen Lake and Stream Monitoring Programs engage over 1,300 people to monitor water clarity once a week from April-September each year. Data collected by participants are used by the state to assess compliance with water quality standards and to track changes in water clarity over time. Monitoring is quick and easy, and the MPCA provides equipment and instructions free of charge.
