At a meeting in Bismarck, Sen. John Hoeven urged General Michael Walsh of the U.S. Army Corps of Engineers and representatives from the federal agencies responsible for flood prevention in the Devils Lake Basin to do all they can to help expedite flood relief for Devils Lake while managing flows to adequately protect downstream interests.
The plan now under consideration includes four key parts:
- Constructing an east end outlet on Devils Lake, which is scheduled for completion next June and will remove up to 350 cubic feet of water per second (cfs).
- Expanding the lake’s existing west-end outlet by increasing capacity from 250 cfs to 350 cfs.
- Building a water control structure at Tolna Coulee that will allow Stump Lake to naturally erode and release water without having a catastrophic flood that would send water uncontrolled down the Sheyenne River and cause extensive damage to downstream communities.
- Constructing a gravity flow outlet consisting of a one-mile-long, 40-foot-wide channel connecting west Stump Lake to Tolna Coulee. This outlet would increase discharges as the lake’s elevation increases.
Devils Lake has risen 32 feet and nearly quadrupled in size since the early 1990s.
