About this program

The Department of the Interior Bureau of Reclamation funds development of hydrologic data, water management tools, and modeling and forecasting capabilities through the Applied Science Grants program (CFDA 15.557), with the most recent award dated May 13, 2025, and an open solicitation (R25AS00280) due August 3, 2026.

The program funds concrete water management outcomes: hydrologic databases and data platforms; operational models for reservoir and irrigation operations; streamflow and water supply forecasting systems; groundwater availability and flow models; decision-support dashboards for water managers; snow monitoring technology integration; geospatial data platforms; and analyses of surface-water and groundwater interactions. Recent awards span isotope-based tracer tools for drinking water systems, drought resilience platforms, cloud seeding feasibility studies, leak detection frameworks for water distribution networks, and ecosystem restoration planning tools incorporating hydrologic data.

Awards are predominantly Project Grants (87 percent of 115 awards), with a smaller share of Cooperative Agreements (13 percent). The Bureau of Reclamation is the sole funding agency under this listing, obligating $20.1 million in federal dollars across 115 awards since 2011. Recipients have contributed an additional $21.7 million in non-federal cost-share, bringing total obligated funds to $41.8 million. Recent award magnitudes range from approximately $48,000 to $1.1 million, with typical awards in the $400,000 to $700,000 range. Award volume has been variable: 6 awards in 2021, 20 in 2022, 7 in 2023, 48 in 2024, and 3 through May 2025.

Representative recent awards include the University of Texas at Arlington and Tarrant Regional Water District developing an isotope-based tracer tool for drinking water blending analysis ($638,558, May 2025); Grant County Conservation District compiling groundwater data for the Columbia Basin via a web resource ($202,703, February 2025); Water District 63 in Idaho expanding drain monitoring and hydrologic modeling for the Boise River Basin ($783,962, February 2025); and the Clark Fork Coalition creating a web-based decision support tool for instream flow and water quality management in Montana ($187,234, August 2024).

The current open opportunity (R25AS00280, due August 3, 2026) solicits eligible states, tribes, irrigation districts, water districts, universities, nonprofits, and organizations with water or power delivery authority for cost-shared projects. The program requires mandatory non-federal cost-sharing. Pre-application coordination with program staff is highly encouraged but not required.

The objective of the Applied Science Grants is to provide funding to non-Federal entities for the development of tools and information to support water management. Eligible projects include the development of modeling and forecasting tools, hydrologi

Description

The Applied Science Grants provides funding to non-Federal entities to improve access to and use of hydrologic data, develop and improve water management tools, and improve hydrologic modeling and forecasting capabilities. Water managers and reservoir operators rely on hydrologic data, modeling, and water supply forecasts to make decisions to meet future water demands. Water supply forecasts are estimates of current and future water supplies based on measured basin conditions (e.g., such as the quantity of upstream mountain snowpack). Results from these projects will be used by water managers to increase water supply reliability to meet water delivery requirements (e.g., compacts, decrees, etc.), provide flexibility in water operations to be more resilient during droughts, and enhance water supply forecasts to better predict floods and optimize limited water supplies. Example projects include improving operational models for irrigation water deliveries or reservoir operations, improving the use of snow monitoring technologies to enhance the skill of water supply forecasts, and improving data acquisition, data analysis, and data delivery, including the development of hydrologic databases.

Eligibility

Applicant eligibility

See above.

Beneficiary eligibility

General public, entities with water or power delivery authority, state, county, and local governmental entities, Tribes, watershed groups, nonprofit conservation organizations and other entities located in eligible states and territories previously described in applicant eligibility.

Uses of assistance

Through Applied Science Grants, Reclamation provides cost-shared financial assistance on a competitive basis for projects to develop tools and information for: (1) assessing water availability and quality, (2) assessing risks to water supplies from drought and other water management challenges (e.g., invasive species, sedimentation, managing to meet competing water demands, meeting endangered species requirements, etc.), and (3) assessing and evaluating watershed management practices.

Length and time phasing of assistance

Proposed projects should be completed within 2 years from the project start date.

How to apply

Preapplication coordination

None. Preapplication coordination is not required but is highly encouraged. Potential applicants can contact Reclamation program staff to discuss their project. Contact information can be found at https://www.usbr.gov/watersmart.

Criteria for selecting proposals

Criteria are specified in the Notice of Funding Opportunity. For more information, see https://www.usbr.gov./watersmart.

Award procedure

Proposals received in response to the funding opportunity are reviewed through a competitive, merit-based review process, and are rated in accordance with the evaluation criteria stated in the funding opportunity. Reclamation will make awards to the highest rated proposals based on the amount of funding available each year.

Deadlines

Deadlines are identified in the Notice of Funding Opportunity and vary from year to year. Contact the headquarters or regional location, as appropriate for application deadlines.

Time to approval or disapproval

See Reclamation's WaterSMART website, https://www.usbr.gov/watersmart/, for additional schedule information.

Appeals

Upon request, Reclamation will provide all applicants with information on why their proposals were not selected.
