The bill strengthens federal oversight of the Lower Yellowstone Fish Bypass Channel, ensuring the Bureau of Reclamation's sole control and funding responsibility for maintenance and repairs. It authorizes the Secretary of the Interior to receive $1,000,000 annually for the channel, with biennial reporting to congressional committees. Importantly, it emphasizes that the act doesn't alter the Lower Yellowstone Irrigation Project's purposes, water rights, contracts, or agreements, nor impose new regulatory obligations or modify state water law. It also doesn't change federal agencies' obligations under the Endangered Species Act or the National Environmental Policy Act.
