The Yuma Field Office manages 1.2 million acres of southwestern Arizona and southeastern California. The area includes 155 miles of the lower Colorado River, a destination for hundreds of thousands of visitors seeking water-related recreation year-round. In winter, the desert becomes a small city as long-term campers escape the northern winter.

The river and desert provide habitat for desert bighorn sheep, Yuma clapper rail, flat-tailed horned lizard, and other wildlife, as well as wild burros and horses.

The field office oversees four wilderness areas, along with significant archeological and historic sites. It is home to Juan Bautista de Anza National Historic Trail, three Areas of Critical Environmental Concern, five properties listed on the National Register of Historic Places and Betty’s Kitchen National Recreation Trail.

The Yuma Field Office is part of the Colorado River District.
