Photos: Dam modifications restore wildlife habitat

Lowhead dam modification
Work was ongoing Tuesday, Feb. 7, 2012, to convert a lowhead dam on the Red River to a spillway dam not far from the Oxbow, N.D., Country Club. Retrofitting dangerous dams on the Red River will improve fish habitat and boater safety.

The state Department of Natural Resources is modifying dams on the Red River northwest Minnesota to reconnect hundreds of miles of fish habitat for the first time in decades. Many of these dams were built to hold pools for city drinking water supplies during the extended drought of the 1930s.
