Manston Slough Restoration

The Manston Slough Restoration Project is a cooperative undertaking between the Buffalo-Red River Watershed District, the MN Department of Natural Resources (DNR), the Minnesota Board of Water and Soil Resources (BWSR), the United States Department of Natural Resources Conservation Service (NRCS), and the United States Fish and Wildlife Service (USFWS). The project was designed to restore the natural hydrology of a large partially drained wetland in Manston Township, Wilkin County, MN.  The project site is approximately two miles wide in the east-west direction and four miles long in the north-south direction. A large portion of the Manston Slough project area includes land owned by the USFWS and DNR.

The project features include a low hazard classification dam with 4,340 acre-feet of storage below the Emergency Spillway Crest, 1,147 acres of wetland restoration, a water level control structure to manage wetland elevations, and  upland watershed treatment to control erosion.
