Opportunity Summary:
The "Colorado River Basinwide and Basin States Salinity Control Program" grant opportunity (Funding Opportunity Number R15AS00037) was offered by the U.S. Department of the Interior, Bureau of Reclamation, to support projects that reduce salinity (salt loading) in the Colorado River system. The program exists to help meet the Colorado River Basin Water Quality Standards, which include an implementation plan intended to prevent further degradation of water quality in a river system that supplies major municipal, agricultural, and industrial water uses across the Southwest, including southern California, Arizona, Nevada, and New Mexico. In practical terms, the opportunity targets work that can measurably lower the amount of salt entering or accumulating in the basin, with an emphasis on cost-effective, regionally scalable solutions rather than isolated fixes.
The funding instrument types listed for this opportunity were grants and cooperative agreements, signaling that awards could range from more independent, recipient-led projects (typical of grants) to more collaborative arrangements where the Bureau of Reclamation may have substantial involvement in technical direction or project execution (typical of cooperative agreements). The funding activity categories tied to the announcement reflect the cross-cutting nature of salinity control: agriculture (where irrigation practices can mobilize salts), natural resources and environment (where watershed and soil processes drive salinity), community development (because water quality affects local economies and infrastructure), and science and technology/research and development (to improve salt-reduction methods and evaluate performance). The category explanation is straightforward: the core purpose is salt reduction in the Colorado River.
Financially, the announcement estimated a total of $36,000,000 available, with an expected six awards. Individual awards were anticipated to fall between an award floor of $1,000 and an award ceiling of $6,000,000, which suggests the program could support both smaller targeted efforts and large, multi-year, multi-partner projects depending on the proposal scope. There was no cost-sharing or matching requirement indicated, meaning applicants were not required to provide a non-federal match to be eligible, although applicants sometimes still choose to leverage additional funds or in-kind support to strengthen competitiveness.
Eligibility was broad and included state governments; county, city/township, special district governments; federally recognized tribal governments and other tribal organizations; nonprofit organizations both with and without 501(c)(3) status (excluding institutions of higher education in the 501(c)(3) category as listed); individuals; and other public entities as specified. This wide eligibility aligns with how salinity sources and solutions are distributed across jurisdictions and land ownership patterns in the basin, and it allows for proposals ranging from public works and watershed improvements to on-the-ground agricultural conservation measures and applied research or monitoring initiatives.
Administratively, the opportunity was posted on April 27, 2015, with an original and current closing date of July 17, 2015, and an archive date of July 20, 2015, indicating the application window has closed and the opportunity is no longer active in its 2015 form. The CFDA (now commonly referenced as Assistance Listing) number associated with the program is 15.509, titled "Title II, Colorado River Basin Salinity Control Program," which is the federal assistance program underpinning this funding opportunity. Applicants were directed to Grants.gov for full announcement materials, and the listed point of contact for access issues or questions was Heidi Hansen, Grants Officer at the Bureau of Reclamation (801-524-3760, heidihansen@usbr.gov).
Frequently Asked Questions (FAQs)
What is the "Colorado River Basinwide and Basin States Salinity Control Program" grant opportunity?
It is a U.S. Department of the Interior, Bureau of Reclamation funding opportunity (Funding Opportunity Number R15AS00037) intended to support projects that reduce salinity (salt loading) in the Colorado River system.
What problem is this funding intended to address?
The opportunity focuses on reducing the amount of salt entering or accumulating in the Colorado River Basin. The goal is to help meet the Colorado River Basin Water Quality Standards and to prevent further degradation of water quality in a river system used for major municipal, agricultural, and industrial water needs across the Southwest.
What is meant by "salinity control" in this program?
In this context, salinity control refers to actions and projects that measurably lower salt loading in the Colorado River system, meaning they reduce the amount of salt contributed to, transported by, or built up within the basin.
What types of projects does the opportunity emphasize?
The opportunity emphasizes cost-effective, regionally scalable solutions that can measurably reduce salinity, rather than isolated fixes that do not translate well across the broader basin.
Which states and areas are highlighted as beneficiaries of improved water quality?
The description highlights major uses across the Southwest, including southern California, Arizona, Nevada, and New Mexico.
Who offered this funding opportunity?
The opportunity was offered by the U.S. Department of the Interior, Bureau of Reclamation.
What are the available funding instrument types?

The opportunity is tied to multiple categories reflecting the cross-cutting nature of salinity control: agriculture; natural resources and environment; community development; and science and technology/research and development.
Why are agriculture and environmental categories included?
The description links agriculture to irrigation practices that can mobilize salts, and natural resources/environment to watershed and soil processes that influence salinity in the basin.
Why are community development and research categories included?
Community development is included because water quality affects local economies and infrastructure. Science and technology/research and development is included to improve salt-reduction methods and evaluate performance.
How much total funding was estimated to be available?
The announcement estimated a total of $36,000,000 available.
How many awards were expected?
The announcement anticipated an expected six awards.
What was the minimum and maximum anticipated award size?
