The Department of the Interior announced $889 million in investments for water infrastructure projects across the Western United States, made possible by the One Big Beautiful Bill Act signed into law by former President Trump in 2025. The funding will support Bureau of Reclamation projects in California, Idaho, North Dakota, South Dakota, Utah, and Wyoming that improve water conveyance, expand storage, and modernize aging infrastructure.

Why it matters

These investments aim to strengthen water security, modernize aging infrastructure, and support the farmers, communities, and industries that depend on reliable water supplies across the Western U.S. By helping ensure strong agricultural production and efficient water delivery, the projects are also expected to contribute to more stable and affordable food prices for American families.

The details

The largest allocation of $540 million will go to California projects, including $235 million for the Delta-Mendota Canal, $200 million for the Friant-Kern Canal, $50 million for the San Luis Canal, and $15 million for the Tehama-Colusa Canal Authority pumping plant. An additional $40 million will support planning and preconstruction activities for raising Shasta Dam. Other major projects include $100 million each for the Eastern North Dakota Alternate Water Supply, the Highline Canal replacement in Utah, and long-term repairs to the Fort Laramie Tunnels in Wyoming.
