Sargent No 1 is a privately owned irrigation dam located in Coalville, Utah, along the Elkhorn Ditch. Constructed in 1956 by the USDA NRCS, this earth dam stands at a hydraulic height of 31 feet and a structural height of 36 feet, with a length of 600 feet. It serves the primary purpose of irrigation, storing 120 acre-feet of water with a normal storage capacity of 90 acre-feet. Despite its low hazard potential, the dam is regulated by the Utah Division of Water Rights and undergoes state inspection, enforcement, and permitting.

The dam's location in Summit County, Utah, makes it a vital resource for water management in the region, with a drainage area of 0.3 square miles and a maximum discharge of 5 cubic feet per second. While the dam's condition assessment is currently not rated, it has a regular inspection frequency of every 5 years, with the last inspection conducted in July 2016. Sargent No 1's emergency action plan status, risk assessment, and management measures are not fully documented, but its low hazard potential suggests a relatively low level of risk associated with the structure.

Overall, Sargent No 1 plays a crucial role in supporting agricultural activities in the area through irrigation water storage. Its design by the USDA NRCS and regulation by the Utah Division of Water Rights ensure that it meets safety standards and operational requirements. With its modest scale and low hazard potential, the dam serves as a significant yet manageable component of the local water resource infrastructure, contributing to the sustainable management of water in the region.
