Joyce is a privately owned irrigation dam located in Coalville, Utah, on Chalk Creek. Built in 1951, this Earth-type dam stands at a hydraulic height of 22 feet and a structural height of 27 feet, with a length of 440 feet. It serves the primary purpose of irrigation, with a storage capacity of 450 acre-feet and a drainage area of 1.2 square miles. The dam has a low hazard potential and has not been rated for condition assessment.

Operated by the Utah Division of Water Rights, Joyce is regulated, permitted, inspected, and enforced by the state authorities. Its last inspection was conducted in July 2018 with a frequency of every 5 years. Situated in Summit County, Utah, this dam is under the jurisdiction of the state and meets all regulatory requirements. The surrounding area is sparsely populated, and the dam poses minimal risk to the community. Although not extensively studied for risk assessment, Joyce remains a critical infrastructure for water resource management in the region.
