The Bureau of Reclamation (Reclamation), part of the Department of the Interior, is responsible for the construction and operation of hundreds of large dams and water diversion structures in the 17 western Reclamation States, as designated in statute (43 U.S.C. §391). Reclamation is the largest wholesale supplier of water in these 17 states and the second-largest hydroelectric power producer in the nation.
Reclamation's Water and Related Resources account funds most agency activities, as well as the agency's programmatic and grant authorities (e.g., water reuse and recycling, desalination, and conservation/efficiency, among other purposes). Reclamation also receives funding for three smaller accounts: California Bay-Delta Restoration, the Central Valley Project Restoration Fund (which is offset by customer receipts), and Policy and Administration.
Administrations typically have requested a lower amount for Reclamation than the final enacted total of annual appropriations. The FY2026 budget proposed $1.273 billion in current budget authority for Reclamation, or $587 million (32%) less than the $1.860 billion Congress approved for FY2025 in the Full-Year Continuing Appropriations and Extensions Act, 2025 (P.L. 119-4; the full-year continuing resolution [CR]). FY2026 Energy and Water Development appropriations bill proposals all provided more funding than the Administration's budget request for Reclamation, including $1.627 billion in the final enacted bill (P.L. 119-74; see Figure 1).

Congress has approved supplemental appropriations for Reclamation in three separate bills since 2020: the Infrastructure Investment and Jobs Act (P.L. 117-58; IIJA) included $8.3 billion total, made available in equal installments from FY2022 to FY2026 (i.e., $1.660 billion per year); P.L. 117-169 (also known as the Inflation Reduction Act) provided Reclamation with $4.590 billion in funding (available through FY2026 or FY2031), $4.0 billion of which was for western drought mitigation; and P.L. 119-21 included $1.000 billion to Reclamation for FY2025 (available through FY2034) for projects that increase the capacity of Reclamation surface water storage projects.
Reclamation's Water and Related Resources account consists largely of individual project funding lines. During the 112th-116th Congresses, Reclamation appropriations were subject to general earmark moratoriums that restricted Congress from funding geographically specific project line items not requested by the Administration. Instead, Congress included additional funding amounts for specified categories of Reclamation projects, such as Rural Water, Water Conservation and Delivery, Environmental Restoration and Compliance, Fish Passage/Fish Screens, and Facilities Maintenance and Rehabilitation. The Administration allocated these funds for specific projects in spend plans made available several months after enactment of the appropriations bills.
In the 117th and 118th Congresses, Congress recommended earmarks (now categorized as community project funding [CPF] or congressionally directed spending [CDS] in the House and Senate, respectively), in addition to amounts designated as additional funding (i.e., funding to be allocated in subsequent work plans). For FY2025, the enacted CR approved no new CPF/CDS projects. In P.L. 119-74, Congress once again included these projects. Recent CPF/CDS and additional funding levels are shown in Figure 2.

Section 4007 of the Water Infrastructure Improvements for the Nation Act (WIIN Act; P.L. 114-322) authorized a process for Reclamation to study and construct federal and nonfederal water storage projects. For projects to receive funding under Section 4007, Congress first appropriates funds under this authority. Then, the Administration recommends specific projects to fund using those appropriations. Congress must approve recommendations by project in enacted appropriations legislation.
From FY2017 through FY2025, Congress provided approximately $988 million total in regular appropriations for these projects. As of late 2025, Congress had approved $948 million of this funding for 13 projects in California, Washington, and Idaho. The FY2026 request included no new funding for Section 4007 projects. The FY2026 enacted bill approved the allocation of $50 million in prior-year appropriations for two Section 4007 projects ($31.8 million for B. F. Sisk Dam Raise and $18.2 million for Sites Reservoir), and the conference report for P.L. 119-74 stipulated that $62.5 million in FY2026 enacted appropriations for water conservation and delivery activities go toward future Section 4007 projects.
Reclamation combines funding for six subprograms (many of them awarded as grants) that promote water conservation into one program—the WaterSMART program. The subprograms are WaterSMART Grants, Title XVI projects (i.e., water recycling and reuse projects), the Drought Response Program, Water Conservation Field Services, the Cooperative Watershed Management Program, Basin Studies, and Aquatic Ecosystem Restoration Grants. For FY2026, the President's budget requested no funding for WaterSMART. P.L. 119-74 provided $41 million for WaterSMART, which was less than the House and Senate proposals (Figure 3).
