Surface Water Integrated Monitoring System (SWIMS)

The Surface Water Integrated Monitoring System (SWIMS) is a DNR system that holds chemistry (water, sediment, fish tissue) data, physical data, biological (macroinvertebrate, aquatic invasives) data and more. SWIMS is the state's repository of monitoring data for Clean Water Act work and is the source of data sharing through the Water Quality Exchange Network [exit DNR]. Department fisheries and water quality biologists use the system to locate monitoring stations, store water quality data and link to fisheries datasets housed at the U.S. Geological Survey. SWIMS is also used by citizen volunteers to store monitoring results for lakes, streams and wetlands.
