Yearns is a Federal-owned earth dam located in Manti, Utah, completed in 1924 for purposes other than irrigation or water supply. The dam stands 15 feet high with a capacity of 100 acre-feet and is situated on the Manti Canyon stream. Despite its low hazard potential, Yearns has a moderate risk rating due to its age and lack of recent condition assessments. The Utah Division of Water Rights oversees state regulation, permitting, inspection, and enforcement of the dam, ensuring its safety and compliance with water resource management standards.

Although Yearns does not have a controlled spillway or outlet gates, its uncontrolled spillway and low hazard potential suggest a relatively stable structure. The dam has not been modified in recent years and is subject to regular inspections every 10 years, with the last one conducted in August 2019. The risk management measures for Yearns are currently unspecified, indicating a need for further assessment and potentially the development of an Emergency Action Plan to address any potential risks associated with the dam's aging infrastructure.

Climate and water resource enthusiasts interested in Yearns can appreciate its historical significance as a Federal-owned structure providing water management in the Sanpete County area. The dam's location in a scenic canyon, combined with its unique design and purpose, make it a noteworthy site for studying the intersection of water infrastructure and environmental conservation efforts. With proper regulatory oversight and regular inspections, Yearns continues to serve its intended purpose while highlighting the importance of maintaining aging dams for water resource sustainability in the region.
