The Citizen Lake and Stream Monitoring Programs are proud to support some of the most dedicated water monitors in the country. The high quality data you collect has helped Minnesota better understand and protect our treasured waterways.
It started in 1998 with 17 volunteers monitoring the health of 22 streams sites in southeast Minnesota. Today there are more than 400 volunteers and 500 stream sites across Minnesota. The data they collect are indispensable to the Minnesota Pollution Control Agency (MPCA).
Volunteers in this program adopt a stream site, tracking how clear the water is weekly during the summer. They use a simple tool called a Secchi tube to measure the clarity, reporting the measurements and their observations to the MPCA. The agency then uses the information to help assess whether the streams meet water quality standards designed to make sure they’re fishable and swimmable.
