This agreement provides support to the state of idaho to implement its nonpoint source management program, focusing on watersheds with water quality impairments caused by nonpoint source pollution

The Environmental Protection Agency Region 10 awarded the State of Idaho Department of Environmental Quality $3.319 million on January 1, 2026, under the Nonpoint Source Implementation Grants program (CFDA 66.460) to implement Idaho's nonpoint source management program across watersheds with water quality impairments.

The funding supports nine subaward projects that implement on-the-ground best management practices designed to reduce nonpoint source pollution. Work includes habitat improvements, agricultural best management practices to reduce thermal loading, nutrients, and stream sediment, and stream stabilization and restoration projects. The state will also host a water quality workshop and use a portion of funding to manage the nonpoint source program. Deliverables include an annual report describing grant-funded work, data input to the National Nonpoint Source Database, and the workshop. Expected environmental outcomes include reductions in sediment, thermal loading, nitrogen, and phosphorous across the nine subawards.

One subaward went to Lewis Soil Conservation District, awarded April 15, 2026, to work with at least eight private agricultural producers in Lewis County's Big Canyon and Lawyer Creek watersheds (tributaries to the Clearwater River) to install livestock management practices, erosion-control structures, and nutrient-management systems addressing TMDL-listed pollutants.

A second subaward went to Soil & Water Conservation Dist, awarded April 8, 2026, to implement projects west of Cottonwood across the Cottonwood Creek and Lawyer Creek watersheds in collaboration with three local road districts.

Performance occurs statewide across Idaho from January 1, 2026, through December 31, 2031.

The state's nonpoint source implementation projects include a variety of structural and non-structural best management practices (BMPS), watershed planning, monitoring, technology demonstrations, and a variety of education/outreach programs. Activities:the proposed work in this agreement includes: nine projects that will support implementation of habitat improvements and farming best management practices to reduce thermal loading, nutrients and stream sediment as well as conserve water for in stream uses. The state will also host a water quality workshop. The state will also use a portion of the funding for managing their nonpoint source program. Subrecipient:the nine subawards funded under this grant will support implementation of on-the-ground best management practices designed to reduce nonpoint source pollution through implementation of agricultural BMPS and steam stabilization and restoration projects.outcomes:the anticipated deliverables include an annual report that describes the work that has occurred under the grant, data input to the national nonpoint source database and a water quality workshop. The expected environmental outcomes include reductions in sediment, thermal loading, nitrogen and phosphorous from nine subawards to local entities. The intended beneficiaries are cleaner water and improved habitat for aquatic species across the state of idaho and all state residents and occupants who benefit from cleaner water and healthier streams, both permanent and temporary.
