SNAKE RIVER, Wash. – The U.S. Army Corps of Engineers’ Walla Walla District has issued revised Master Plans for the Lower Monumental and Little Goose Projects. Each Master Plan includes a Finding of No Significant Impact (FONSI) and an Environmental Assessment (EA). The Master Plans were updated because the original Master Plans were more than 50 years old and there have been changes in policy and management strategies over that time.
