The links below provide access to some of the more recent reports and work plans prepared by the MDA. Many older reports are available in the Minnesota Water Research Digital Library or by contacting the email under Contact Us.
Most of the historic pesticide and nutrient monitoring data collected by the MDA is available at the Water Quality Portal. The Water Quality Portal is a cooperative service sponsored by the United States Geological Service (USGS), The Environmental Protection Agency (EPA), and the National Water Quality Monitoring Council (NWQMC). It serves data collected by over 400 state, federal, tribal and local agencies. Water quality monitoring data is also available by contacting the email under the Contact Us link.
