    Continuing Authorities Program: Aquatic Ecosystem Restoration – Section 1135, Sand Hill River

    The study area is located in a rural setting in Polk County, Minnesota, 275 miles northwest of Minneapolis, Minnesota. The Sand Hill River basin is centrally located in the Red River Valley watershed. A major reach of the river downstream of Fertile, Minnesota, was the subject of a flood control project constructed by the Corps of Engineers from 1955 to 1958. It involved straightening the river and constructing several drop structures and served as a drainage improvement to local agriculture. Overall, more than 18 miles of the Sand Hill River was straightened or abandoned.
