Determine whether or not continued operation and ownership of Upper St. Anthony Falls Lock and Dam (USAF) is in the federal interest, and if not, provide supporting information for deauthorization of the project purposes and disposal of the property. USAF is located on the Mississippi River in Minneapolis, Minnesota.
The hydrology in the area has changed significantly, driven in part by change in land use and climate. The proposed project aims to improve habitat for aquatic vegetation and migratory waterfowl by providing water level management capabilities that target management goals of the refuge. This study area is located within the Minnesota Valley National Wildlife Refuge in an urban floodplain area near the cities of Shakopee and Savage, Minnesota. The lake and marsh areas are south of the Minnesota River (river miles 15‒21) and include Blue Lake, Fisher Lake, Rice Lake and the adjacent Continental Grain Marsh.
