Southwestern Division, established in 1937 to manage large-scale construction projects authorized by the Flood Control Act of 1936, is headquartered in Dallas, Texas, with district offices in Fort Worth and Galveston, Texas; Little Rock, Arkansas; and Tulsa, Oklahoma. Our regional team has grown in expertise and missions, overseeing hundreds of water resources development, military design and construction projects.

The division manages 2.3 million acres of public land and water, and is committed to being a good steward of our Nation’s financial and environmental resources and to providing top-quality service to the people of the Southwest, and seamless service to the Nation. The Division performs water resources development and management activities in all or part of Arkansas, Kansas, Louisiana, Missouri, Oklahoma, and Texas, and has Military Program responsibilities in Arkansas, Louisiana, Oklahoma, Texas, and part of New Mexico.

Most of our work falls into three major mission areas: Civil Works, which includes in-part, flood damage reduction, navigation, hydropower, water supply, recreation, regulatory, and disaster relief; Military Programs, which includes engineering, construction, and environmental management services for the Army and Air Force, and engineering support for Army Transformation; and, International and Interagency Services, which includes planning, and engineering and construction management services for other federal, state and local agencies.
