Lower Yellowstone River Native Fish Conservation Act
Summary
S. 3409 would reaffirm that the federal Bureau of Reclamation retains exclusive ownership, operational control, and financial responsibility for the Lower Yellowstone Fish Bypass Channel in eastern Montana. The bypass channel was authorized in 2007 and completed in 2022 to protect the endangered pallid sturgeon and other native fish species in the Yellowstone River. The bill would explicitly prohibit the Lower Yellowstone Irrigation District and Project from being required to fund or participate in activities related to the bypass channel or endangered species conservation efforts associated with it. The bill would also direct federal coordination with state and wildlife agencies to ensure conservation measures are maintained without burdening local irrigation operations. The Lower Yellowstone Irrigation Project provides water to approximately 58,000 to 59,000 acres of farmland in eastern Montana and western North Dakota. Supporters argue the bill protects farmers and ranchers from unexpected costs while maintaining environmental protections for the endangered sturgeon. The bill is currently under consideration in the Senate Committee on Energy and Natural Resources Subcommittee on Water and Power, which held hearings on it in March 2026.
