Public Access to Water Quality Data

Promoting clean water is a community endeavor. Therefore, our stream monitoring program is based on the philosophy that volunteer-collected data should be accessible to all citizens in the Rock River Basin and, indeed, across the state to enhance watershed management decision-making. All stream monitoring data is uploaded onto a state-wide databases that can be accessed and analyzed by all Wisconsin citizens. The database is maintained by the WDNR and is called Surface Water Integrated Monitoring System. Check out these data delivery tools.
