River Science at Wisconsin DNR

The Wisconsin Department of Natural Resources is responsible for implementing the Clean Water Act, ensuring healthy fisheries, and managing and supporting aquatic ecosystems. As part of this work the DNR conducts research to better understand and support river systems. The Science Services Program supports researchers who design and evaluate tools needed to measure ecosystem health or to prevent or reduce the health of aquatic communities. The map below illustrates one product of this work: Streams Natural Communities of Wisconsin, a GIS datalayer derived from analytical modeling that predicts stream flow and temperature, two controlling factors in stream community composition, structure and biotic assemblage [View Douglas County Map [PDF]].

Areas of fish and habitat research include: Biological Indicies, Habitat, Management & Regulation, Propagation and Citizen Monitoring.
