US Army Corps of Engineers
Walla Walla District Website

The Corps is using the latest technology to develop tools that communities in Idaho can use to predict flooding. The technology: Two-dimensional modelling.
The U.S. Army Corps of Engineers’ Walla Walla District completed repairs for the Dayton Levee Project on Nov. 16 and began repairs on the Milton-Freewater Levee Project on Nov. 18.
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.
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.
