Funded Projects

Examples of what this program has supported.

FY2024 FY24 appropriations were allocated to the Sites Reservoir Project.
FY2025 Appropriations are expected to be allocated to eligible projects such as the B.F. Sisk Dam Raise and Reservoir Expansion Project.

Program Objective

Section 4007 of Public Law 114-322, also known as The Water Infrastructure Improvements for the Nation (WIIN) Act allows the Secretary of the Interior to negotiate and enter into an agreement on behalf of the United States for the design, study and construction or expansion of federally owned or State-led water storage project. The Secretary may participate in a federally owned storage project “in an amount equal to not more than 50 percent of the total cost of the federally owned storage project,” (4007(b)(2)) and may participate in a State-led storage project “in an amount equal to not more than 25 percent of the total cost of the State-led storage project” (4007(c)(1)). In return for this cost-share, “at least a proportional share of the project benefits are the Federal benefits, including water supplies dedicated to specific purposes such as environmental enhancement and wildlife refuges” (4007(c)(2)(C)). To be eligible for funding, the Secretary of the Interior must have determined the project to be feasible before January 1, 2021.

Use of Funds

Allowed Uses

The WIIN Act Section 4007(b) allows the Secretary to participate in federally owned storage projects in a Reclamation State to which the United States holds title and that was authorized to be constructed, operated and maintained pursuant to reclamation laws.

The WIIN Act Section 4007(c) allows the Secretary to participate in State-led water storage projects that are constructed, operated, and maintained by a State agency or agency organized pursuant to State law and provide a benefit in meeting any obligation under Federal law, including regulations.

Required Documentation

To be eligible to receive funding for construction activities, a water storage project must be specifically authorized under the amendments in section 4007 of the Water Infrastructure Improvements for the Nation (WIIN) Act and the Secretary of the Interior must have determined the project to be feasible before January 1, 2021.

Reclamation will proceed with expenditure of construction funding once a project has been found feasible, a cost sharing agreement has been signed with a non-Federal partner for a construction project, all appropriate regulatory and contractual requirements have been met, and the project has been named in appropriations legislation.

These include: (1) a finding that the feasibility study meets the requirements the of WIIN Act; (2) complete compliance with the National Environmental Policy Act and other environmental clearances; (3) a financial feasibility determination; (4) an executed cooperative agreement for financial assistance, and (5) appropriate contracts to ensure Federal benefits will be realized in accordance with the WIIN Act. 2 CFR 200, Subpart E - Cost Principles applies to this program.

Matching Requirements

The Secretary may participate in a federally owned storage project “in an amount equal to not more than 50 percent of the total cost of the federally owned storage project,” (4007(b)(2)) and may participate in a State-led storage project “in an amount equal to not more than 25 percent of the total cost of the State-led storage project” (4007(c)(1)). The Federal share of the costs of a project or activity carried out under this Program may vary dependent upon activity and authority. Costs of operation, maintenance, repair and rehabilitation of facilities shall be a non-federal responsibility.
