Soderquist, located in Gunnison County, Colorado, is a private irrigation dam on Willow Creek with a primary purpose of providing water for agricultural use. Built in 1956, this earth dam stands at a height of 24 feet and spans 700 feet in length, storing a maximum of 248 acre-feet of water. Despite its age, Soderquist is in fair condition and has a low hazard potential, as assessed in 2014.

The dam, owned privately, is regulated by the Colorado Department of Water Resources, with state jurisdiction, permitting, inspection, and enforcement in place. While the spillway type is listed as "None," the dam's outlet gates include a slide (sluice gate) and are uncontrolled. Soderquist has a drainage area of 7 square miles and a surface area of 17 acres, serving not only for irrigation but also for fire protection, stock watering, and as a small fish pond.

Although Soderquist poses a high risk due to its condition and age, the dam's emergency action plan status, risk management measures, and inundation maps are not specified in the data. With a capacity to handle a maximum discharge of 900 cubic feet per second, Soderquist remains a crucial water resource in the region, playing a vital role in sustaining agricultural activities and water availability for various purposes in the area.
