Idaho Falls Region

The Idaho Falls Region in southeast Idaho is the second largest of DEQ's regions and includes the counties of Bonneville, Butte, Clark, Custer, Fremont, Jefferson, Lemhi, Madison, and Teton. It covers the second largest geographical area of DEQ's regions, with 21.1% of the total area of the state. For such a large region, only 12.6% of the state's total population resides here. The low population density is attributed to the vast areas of mountains located within the region. Also included in the region are the cities of Idaho Falls, Salmon, Challis, Arco, Rexburg, St. Anthony, and Driggs.

This region is well known for its central Idaho mining and upper Snake River Plain farming. Several active mines are found in this region, and much of the state's sugar beet, wheat, and potato crops are grown here. The area boasts many recreational opportunities as well, from rafting on the Salmon River, fishing at Island Park and the Henry's Fork, to skiing at Targhee near Driggs. The Idaho National Laboratory is the largest employer in the region; agriculture, mining, and tourism/recreation are also important economic forces.
