Sunrise River Watershed Study

Study Focus
A watershed study was performed for the Sunrise River Watershed by the U.S. Army Corps of Engineers, including all areas upstream of the Sunrise River confluence with the St. Croix River. The study focused on priority water resource issues identified through collaboration with Chisago County, Minnesota Pollution Control Agency, and stakeholders. This included evaluating existing conditions for water quality; aquatic habitat; wetlands presence and historical loss; geomorphic conditions; and groundwater / surface water interactions.

The potential for future development was assessed, including potential impact of future land use on phosphorus and sediment loading. Various land use scenarios were considered to assess potential for reduced future phosphorus loading from the watershed. Finally, recommendations were made to direct future watershed planning.
