Summary

The Secretary may agree to help pay for the design, study, and construction of projects that restore or protect rivers, fish, wildlife, and aquatic habitat in Reclamation States. States, Indian Tribes, irrigation or water districts, water or power authorities, owners of eligible facilities, nonprofit conservation groups working with those owners, and joint state agencies can ask for help. Projects can include fixing fish passage or removing or bypassing barriers like dams. Before any work starts, the public must be allowed to comment. If a project would remove or shrink a dam’s storage or diversion, the dam owner must agree before studies begin, and the Secretary must notify entities that get water or power from the dam before construction. Construction can only move forward if no written objection is received within 120 days from entities that together receive one‑third or more of the water or power. An eligible entity must pay at least 35 percent of construction costs and must pay all operation, maintenance, replacement, and rehabilitation costs. The Secretary must make sure the project won’t cause unmitigated harm to existing water deliveries, the environment, tribal interests, treaties, or interstate compacts, and must follow all federal and state laws (including NEPA, the Endangered Species Act, and subtitle III of title 54). Up to $15,000,000 is authorized for each fiscal year 2022 through 2026. This program does not override other laws, state water law, or interstate compacts. Projects that have broad stakeholder support, benefit multiple river basins or regions, are part of a plan to replace aging facilities, or help restore anadromous fish listed under the Endangered Species Act will be given priority.
