Shiner Lower, also known as Ellsworth Lower, is a privately owned dam located in Idaho's Lemhi County, specifically in the city of YEARIAN. This dam, completed in 1973, serves primarily for irrigation purposes, with a normal storage capacity of 50 acre-feet from the Yearian Creek and Lemhi River. The dam stands at a height of 17.5 feet and has a hydraulic height of 13.8 feet, making it a vital structure in managing water resources in the region.

Despite its importance, Shiner Lower faces challenges in terms of its condition assessment, which is rated as poor. The hazard potential is considered low, but the risk assessment is moderate, indicating the need for careful monitoring and maintenance. The last inspection in November 2020 highlighted these concerns, prompting a moderate risk management approach to ensure the dam's structural integrity and the safety of the surrounding area. As water resource and climate enthusiasts, it is crucial to stay informed about the state of dams like Shiner Lower to address potential risks and ensure sustainable water management practices for the future.
