Great Plains Regional Organization:

The Great Plains Region encompasses all or parts of nine states including Montana, North Dakota, South Dakota, Wyoming, Colorado, Nebraska, Kansas, Oklahoma, and Texas.

The Great Plains Region has its roots in three former Reclamation regions: the Upper Missouri Region headquartered in Billings, Montana; the Lower Missouri Region headquartered in Denver, Colorado; and the Southwest Region headquartered in Amarillo, Texas.

In October 1985 the Upper and Lower Missouri regions were merged into the Missouri Basin Region with headquarters in Billings. In 1988 much of the Southwest Region was joined into the Missouri Basin Region and the region's name was changed to Great Plains Region. Geographically, it became the largest of the Reclamation regions.

The Regional Director in Billings is assisted in managing the region by a Deputy Regional Director, Assistant Regional Director, and six Area Managers. Along with the Regional Director's Special Assistant for Native American Affairs, this group comprises the Regional Leadership Board.
