About this program

The Department of the Interior Bureau of Reclamation funds irrigation canal and lateral modernization projects under CFDA 15.509 to reduce salt loading in the Colorado River system, with most recent awards made in May 2024. The program obligated $215.1 million in federal dollars across 89 cooperative agreements and project grants since 2000, with grant activity concentrated in 2020 (11 awards) and 2024 (8 awards). Awards are written for five-year performance periods and predominantly structured as cooperative agreements (81 percent, 72 awards) with a smaller share of project grants (19 percent, 17 awards). All funding comes from Reclamation, which alone finances the entire portfolio.

Awarded projects convert unlined earthen irrigation canals, ditches, and laterals into pressurized buried pipelines within the Upper Basin states—chiefly Colorado, Utah, and Wyoming—to eliminate seepage losses that mobilize naturally occurring salts in formation soils. Recent awards focus on canal lining and piping systems serving irrigation districts and water user associations. Representative recent awards include a cooperative agreement with North Delta Irrigation Company in the Gunnison River Basin to replace and pipe sections of the North Delta Canal, reducing anticipated annual salt load by 3,432 tons at a cost-effectiveness of $73.02 per ton ($5.878 million obligated, completion June 2028); a cooperative agreement for the Bench Canal near Fort Duchesne, Utah, replacing earthen canal with pipeline to reduce approximately 2,087 tons of salt annually at $70.66 per ton ($5.459 million, completion May 2026); and a project grant for wildlife habitat acquisition and management along the Colorado River west of Fruita, Colorado, to mitigate habitat losses from prior salinity control unit construction ($634 thousand, completion September 2029).

Applicants must be legal entities owning or operating irrigation features targeted for replacement and capable of contracting with Reclamation. Projects must be located in the Colorado River Basin above Hoover Dam and demonstrate quantifiable salt reduction. Funding decisions rank proposals by cost-effectiveness (cost per ton of salt prevented), ability to enable future on-farm irrigation improvements with USDA support, technical merit, and performance risk factors. The most recent posted opportunity (R23AS00353, Basinwide & Basin States Salinity Control Programs) closed September 27, 2023. No currently open solicitation is present in the source; applicants should monitor Reclamation's announcements for the next funding cycle.

Objective and description

Objective

To provide financial and technical assistance to: (1) identify salt source areas; (2) develop project plans to carry out conservation practices to reduce salt loads; (3) install conservation practices to reduce salinity levels; (4) carry out researc

Description

The Colorado River Basin Salinity Control Program is a longstanding partnership led by Reclamation that works to reduce the amount of salt entering the Colorado River system, protecting water quality for millions of municipal, industrial, and agricultural users by improving off-farm systems like canal and ditch lining. It serves communities, farmers, local irrigation districts, and water users across all seven Basin States, offering funding, technical coordination, and project support under federal cost-share programs to help keep the river clean and productive. What makes the program unique is its basinwide collaboration among federal agencies, states, tribes, and hundreds of local partners, along with its proven success in removing more than 1.3 million tons of salt from the river system each year through practical, science-based solutions.

Eligibility

Applicant eligibility

Any legal entity that is the owner or operator of the features to be replaced and/or to be constructed and capable of contracting with Reclamation.

Beneficiary eligibility

Any person who uses or reuses Colorado River water for irrigation, domestic, municipal or industrial water supply, or for fish and wildlife habitat will benefit.

Uses of assistance

Eligible owners or operators in the Colorado River Basin above Imperial Dam may receive assistance to treat salinity problems.

Use restrictions

Everything not listed under Use of Assistance, above.

Length and time phasing of assistance

Cooperative agreements and grants are written for a 5-year period.

How to apply

Preapplication coordination

Environmental compliance for this program may be required depending on the scope of the specific project funded. This may result in the need for an environmental impact assessment or environmental impact statement prior to the commencement of project activities.

Criteria for selecting proposals

In 1984, the Salinity Control Act was amended to direct the Secretary of the Interior to give preference to units which reduce salinity at the least cost per unit of salinity reduction (or cost-effectiveness). Cost-effectiveness is defined as the Salinity Program's annual cost per ton of salt prevented from entering the Colorado River system. Conceptually, cost-effectiveness is analogous to determining the cost per mile to own and operate a car. That computation combines the annual expenses (loan payments, gas, maintenance, etc.) and divides by the miles traveled each year. The key to understanding this approach is to appreciate that the government evaluates all projects as if the money is borrowed from a loan institution and repaid in annual installments over the life of the project. This economic evaluation principle is required by the "Economic and Environmental Principles Guidelines for Water and Related Land Resources Implementation Studies," March 1983. This method lends consistency in the comparison of non-federally financed alternatives (which must borrow funds) to Federally financed projects. Each proposal will be evaluated by an application review committee in accordance with the following criteria and corresponding percentage weights: (a) Technical merit - those passing will be evaluated further; (b) Cost effectiveness - 35%, (the annual cost for each ton of salt load reduction, expressed in dollars per ton); (c) The ability to enable future on-farm projects with the USDA - 30%; (d) Performance risk factors- 25%. Detailed information will be included in each FOA or may be obtained from the Salinity Control Program contacts listed above.

Award procedure

Reclamation will solicit proposals and award funding through a Notice of Funding Opportunity process. The NOFO will request proposals from public and private sectors that would control salinity based on cost per ton. The proposals will be ranked based on their cost effectiveness for preventing salt from entering the Colorado River system. The ranking would consider risk factors that might affect the project's performance. Upon receipt of applications/proposals by the date identified in the announcement(s), the applications will be reviewed to determine if application/proposal(s) are consistent with requirements identified in the announcements. The application/proposal(s) are reviewed against identified criteria by a Federal technical team of experts, that may include representatives of states as advisors. Based on the review, a ranking will be defined. Negotiations will be conducted and/or awards will be made based on recommendations from the technical experts. Award will be based on those applications best meeting the needs of the program, including cost and risk factors.

Time to approval or disapproval

Approximately 90 days.

Appeals

Final award decisions are not subject to appeal; however, the Bureau of Reclamation will provide all applicants with information on why their proposals were not selected for award.
