About this program

The Department of the Interior Bureau of Reclamation funds water conservation, hydropower, and small-scale water efficiency improvement projects in the Western United States through WaterSMART (Sustain and Manage America's Resources for Tomorrow), CFDA 15.507, with the most recent grant award issued on February 27, 2026.

WaterSMART funds concrete water management improvements: canal lining and piping to reduce seepage losses; advanced metering infrastructure and supervisory control and data acquisition systems for real-time water flow monitoring and leak detection; water supply planning and design for drought contingency and water strategy documents; riparian habitat restoration and fish passage improvements; and groundwater recharge and storage infrastructure. Recent awards span agricultural irrigation efficiency, municipal water supply reliability, aquatic ecosystem restoration, and drought resilience planning across Western states and territories.

The program is predominantly Project Grants (91% of awards), with a smaller share of Cooperative Agreements (8%). The Department of the Interior Bureau of Reclamation has issued 1,641 awards totaling $716 million in federal dollars obligated, representing 99.9% of program activity; a second federal agency (Department of the Interior) has issued 2 awards for $142 thousand. The portfolio spans 1,643 total awards since 2003, with annual disbursement averaging 130–151 awards per year over the past five years. Combined federal and non-federal dollars obligated total $2.03 billion, indicating substantial cost-share participation from recipients. Recent individual awards range from $49,934 to $10.3 million, with typical magnitudes between $300 thousand and $3 million for implementation projects.

Representative recent awards include the Westlands Water District installing 1,603 advanced meters expected to conserve 4,345 acre-feet annually ($3.66 million, February 2026); the San Diego County Water Authority restoring 42.5 acres of riparian habitat to support threatened and endangered species ($10.3 million, December 2025); and the Northern Nevada Water Authority restoring 10 acres of riparian habitat at Warm Springs Natural Area to protect endangered species and reduce wildfire risk ($1.99 million, February 2026).

Two grant opportunities are currently open. WaterSMART Enhancing Water Resources Projects (R26AS00017) solicits implementation projects balancing multiple water uses and developed collaboratively, with applications due September 8, 2027. Small-Scale Water Efficiency Projects (R25AS00279), posted March 5, 2026, with a due date of June 2, 2026, funds canal lining, automation, flow measurement, and similar efficiency improvements. Applicants must be located in the 17 Western States, Alaska, Hawaii, or U.S. territories; Category A applicants (states, tribes, irrigation and water districts, and other entities with water or power delivery authority) are broadly eligible, with Category B nonprofits required to partner with Category A entities and Category C watershed groups eligible only for environmental restoration work.
