What is PRRSUM?

River research and restoration in the Upper Midwest is an area of intense activity involving federal and local agencies, watershed managers, consultants, researchers, and educators. There is a clear demand for discussion, knowledge exchange, and collaboration between these entities, including two-way exchanges between research and practice as well as interagency communication. The Partnership for River Restoration and Science in the Upper Midwest (PRRSUM, prounounced "prism") is an organization dedicated to bringing together regional river and stream restoration practitioners from throughout the Midwest for knowledge exchange and networking.

PRRSUM strives to help build and formalize a professional stream restoration group in the Midwest region, providing opportunities for networking and collaboration through an annual symposium, webinars, online resources, and other activites.
