What Happened?

Congress has channelled more than $3 billion towards water storage project funding as Western states face decades of drought, shrinking reservoirs, and fights over water rights. According to a Congressional Research Service report published Aug. 12, three separate laws fund the study and construction of new reservoirs and underground water storage systems.

The agency that manages most of that money is the Bureau of Reclamation, the federal office that oversees water infrastructure across 17 western states. The three laws are the Water Infrastructure Improvements for the Nation Act (WIIN Act), the Infrastructure Investment and Jobs Act (IIJA), and the Budget Reconciliation Act of 2025.

Why Does It Matter To Me?

New storage capacity could mean more reliable water supplies for households, agriculture, and communities that depend on rivers and groundwater.

The WIIN Act allows the federal government to cover up to 50 percent of the cost for federally owned storage projects and up to 25 percent for state-led projects. The IIJA added $1.05 billion specifically for water storage, spread across fiscal years 2022 through 2026. The Budget Reconciliation Act of 2025 added more money available through fiscal year 2034.

Both Sides, Now

Supporters of the funding argue that new storage infrastructure is essential for water security in a region where demand routinely outpaces supply. The laws shift project approval authority to congressional appropriations committees, meaning water projects can move forward without going through the House Natural Resources Committee or the Senate Energy and Natural Resources Committee.

Critics of that approach argue that bypassing the traditional authorizing committees reduces oversight and could allow projects to advance without full scrutiny of their environmental or economic impacts. The Congressional Research Service report does not take a side on that question, but it identifies the shift in authority as a notable structural change. Of the 13 projects initially funded under the WIIN Act, only eight met a Jan. 1, 2021, feasibility study deadline. The five that missed it are no longer eligible for ongoing construction funding under that law.

What Happens Next?

The Secretary of the Interior must recommend specific projects to Congress, which then approves them by name in annual spending bills. That means each project still needs a separate act of Congress to receive construction money. With the Budget Reconciliation Act of 2025 funding available through fiscal year 2034, there is time for additional projects to move through the process, but the five projects that missed the 2021 deadline face a narrower path forward unless Congress acts to restore their eligibility.
