AHSAHKA, Idaho – The U.S. Army Corps of Engineers’ Walla Walla District is extending the public comment period on an Environmental Assessment (EA) and draft Finding of No Significant Impact (FONSI) for the “Dworshak Reservoir Nutrient Supplementation Pilot Study.” The comment period extension will now end Saturday, March 17.

The NPDES permit allows application of liquid fertilizer to Dworshak Reservoir as an ecosystem treatment.
