CITY (NewsDakota.com) The U.S. Army Corps of Engineers completed construction of the million Tolna Coulee Control Structure on May 22.

The 800-foot wide structure is designed to regulate the amount of water that would flow through the coulee. The Corps of Engineers says completion of this project eliminates the threat of catastrophic flooding along the Sheyenne River if Stump Lake were to exceed 1,458 feet above sea level. Current lake level is 1,453.24 feet.

The Corps will turn over the project to the North Dakota State Water Commission for the operation and maintenance.

A contract was awarded to International Falls, Minn., based Wagner Construction for $6.5 million in September 2011.
