The SWIMS Database
Our committed citizen volunteers help preserve, protect and restore Wisconsin’s 86,888 miles of streams and rivers by providing valuable scientific data to Wisconsin’s natural resource professionals and community leaders. Data we collect inform decision-making about real-world resource management issues that impact local communities. These data are entered into the WDNR’s public Surface Water Integrated Monitoring System (SWIMS) online database. Anyone with web access can view the data in the database, which is searchable by county, stream or site name.
Station Data Reports
Reports generated from SWIMS help paint a broader picture of water quality in Wisconsin. These station data reports include graphs of volunteers’ site-specific data and explain what the results mean for aquatic organisms. Special Projects Monitoring reports can be accessed under “Nutrient” and “Road Salt” headings.
