JACKSON, Wyo. — The State of Wyoming and the Bureau of Reclamation have reached an agreement on water management operations for the Upper Snake River Basin that will avoid impacts to fisheries below Jackson Lake Dam.

“If necessary, the Bureau of Reclamation has committed to covering any shortfalls should they occur.”  

WGFD press release

According to the Wyoming Game and Fish Department (WGFD), The State of Wyoming will supplement flows in an effort to protect the ecosystem and maintain releases at a minimum of 280 cubic feet per second (cfs). Wyoming is committed to using its water storage allocation, up to a maximum of 33,000-acre feet. If necessary, the Bureau of Reclamation has committed to covering any shortfalls should they occur and pledged to work with Wyoming regarding maintaining adequate flows throughout the year and assessing how operations of Jackson Lake impact Reclamation operations system-wide. 

The minimum flow required to maintain the fishery below the dam and maintain water within the world-famous Oxbow Bend is 280 cfs. The 4.5-mile stretch of river below the dam is critical habitat for Snake River cutthroat trout, shore birds, wildlife and the bluehead sucker. 

“This stretch of river is iconic and a national treasure. I appreciate the Bureau of Reclamation’s efforts to work with us to find solutions to address our concerns” Wyoming Game and Fish Director Brian Nesvik said. “We look forward to working together to examine water operations and ensure water flows are maintained year-long.”

Any reduction of water flow below the prescribed operation in this area could harm the ecosystem and negatively affect angler opportunities.

“The wild and scenic Snake River in Grand Teton National Park provides stunning views, world-class fishing and recreational opportunities and excellent wildlife viewing,” Grand Teton National Park Superintendent Chip Jenkins said. “We appreciate the State of Wyoming and the Bureau of Reclamation’s joint efforts to ensure minimum flows from Jackson Lake Dam to protect these resources and experiences.”
