The Department of the Interior Bureau of Reclamation provides grants and cooperative agreements to federally recognized Indian tribes for developing, managing, and protecting tribal water resources in the 17 western states under CFDA 15.519, with the most recent grant award dated October 1, 2025.

Award activity has remained consistent and robust over the past five years, with 24 grants disbursed in 2025, 19 in 2024, and 37 in 2023. The program has operated continuously since 2000 and shows sustained recent engagement through competitive and non-competitive funding cycles. The portfolio totals $200 million in combined federal dollars obligated across 397 awards spanning more than two decades.

The program funds concrete water-infrastructure and water-management projects: irrigation system rehabilitation and modernization including pump station replacement and pipeline installation; water well drilling, testing, and rehabilitation; water supply diversification and drought resilience planning; stream and groundwater monitoring and water quality assessment; water treatment plant design and drinking-water system improvements; hydroelectric and geotechnical feasibility studies; riparian restoration and erosion control; and aquatic resource monitoring for fisheries management. Representative recent awards include Fort Mojave Indian Tribe's $615 thousand project to replace agricultural irrigation pumps and motors to address drought impacts on Lower Colorado River water supply; Tolowa Dee-ni Nation's $7.9 million multi-year effort to plan and design a tribal domestic drinking-water system near Smith River, California; and Yakama Nation's $300 thousand water resource assessment to inform a management plan for the White Salmon River Basin. Projects typically run one to two years.

Project Grants comprise 91 percent of the portfolio, with Cooperative Agreements making up 9 percent. The Department of the Interior Bureau of Reclamation funded 396 of 397 awards ($199.9 million); the Bureau of Land Management New Mexico Region awarded one small grant ($152 thousand).
