Hiles Canyon, located in Dawson County, Nebraska, is a significant hydroelectric structure with a primary purpose of generating electricity and irrigating surrounding areas. Built in 1941, this earth dam stands at 25 feet in height and stretches 502 feet in length, with a storage capacity of 200 acre-feet. The dam is owned and regulated by the Federal Energy Regulatory Commission and is subject to state oversight by the Nebraska Department of Natural Resources.

The dam's low hazard potential is attributed to its sturdy stone core and soil foundation, providing stability for the structure. With a maximum discharge capacity of 2370 cubic feet per second, Hiles Canyon plays a crucial role in water resource management and flood control in the region. Despite its age, the dam has not been modified in recent years and its condition assessment is currently not available.

Public utility Hiles Canyon serves as a vital infrastructure for the community of Cozad, Nebraska, supporting both hydroelectric power generation and irrigation activities. As a state-regulated and federally-owned facility, the dam undergoes regular inspections by the Federal Energy Regulatory Commission to ensure its safe and efficient operation. With its strategic location on the Supply Canal and its important role in water storage and control, Hiles Canyon remains a key asset for water resource and climate enthusiasts in the region.
