Habitat Management Units, or HMUs, are different from other parks. While parks are maintained to provide recreational opportunities, HMUs are areas of land dedicated to environmental stewardship.
In an effort to stabilize shorelines, protect cultural sites and improve habitat for fish and wildlife, Corps engineers, biologists and environmental scientists have repurposed native coyote willow found below the Mill Creek Diversion Dam at Rooks Park in Walla Walla.
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.
The Walla Walla District constructs, operates, maintains, and secures multipurpose infrastructure to energize the economy, reduce flood risk, and serve as stewards of water resources for the Snake River Basin and the Nation.
