Hebgen Dam flow increasing May 26 to enhance Madison River trout spawning gravel
Date: May 19, 2023
Butte, Mont. – May 19, 2023 – NorthWestern Energy will increase the volume of water releases from Hebgen Dam to flush fine sediments from Madison River gravel to enhance the quality of spawning gravels that support the healthy wild trout fishery.
Hebgen Dam outflows will gradually increase over several days to coincide with peak runoff in the West Fork Madison River and other tributary streams.
The flow release increase is planned to begin May 26 and will continue through the end of May. River recreationists should be aware of the changing conditions and take appropriate precautions.
The Madison River Flushing Flow Program is designed to augment natural river flows with surplus water in good snowpack years.
The 2023 flushing release from Hebgen Dam is a cooperative effort planned by: NorthWestern Energy; Montana Fish, Wildlife & Parks; Montana Department of Environmental Quality; the U.S. Bureau of Land Management; the U.S. Fish and Wildlife Service; and the U.S. Forest Service.
To protect the outlet of Quake Lake from erosion, the Madison River flows will be maintained at about 3,500 cubic feet per second at the Kirby Ranch stream gage.
NorthWestern Energy owns and operates Hebgen and Madison dams on the Madison River under a license issued by the Federal Energy Regulatory Commission.
For questions about the flushing release, contact NorthWestern Energy Manager Hydro License Compliance Andy Welch at 406-444-8115 or Andrew.Welch@northwestern.com.
