The U.S. Army Corps of Engineers has completed environmental compliance for the Dworshak Nutrient Supplementation Project, an “ecosystem improvement project” at Dworshak Reservoir in Idaho.
After review and consideration of recent public comments in accordance with the National Environmental Policy Act, the Corps found that the project would not have significant impacts on the environment.

The U.S. Environmental Protection Agency previously issued a National Pollutant Discharge Elimination System permit to the Corps on Sept. 6, 2011, effective on Oct. 15, 2011, after EPA environmental review and consideration of public comments. The NPDES permit allows application of liquid fertilizer to Dworshak Reservoir as an ecosystem treatment.
The Corps then performed an Environmental Assessment and developed a draft Finding of No Significant Impact for public comments. The Corps initially accepted public comments through Feb. 16 and further extended the public comment period until March 17 to accommodate wider public input.
The Corps is partnering with Idaho Department of Fish and Game on thes project. The Corps plans to resume addition of nutrients to the reservoir this year.
