Colorado River Salinity Control Fix Act

This bill amends the Colorado River Basin Salinity Control Act to adjust federal cost-sharing requirements for salinity control projects. It specifies that the federal government will cover 75-85% of costs for various salinity control units (including on-farm measures), with states covering the remaining portion. The changes apply to projects authorized under existing sections of the law, directly affecting Colorado River Basin states and landowners who implement these measures. A special provision for fiscal years 2024-2025 increases federal coverage for certain projects to 75-85% of costs.
