Located in Bolivar, Tennessee, the Crystal dam is a privately owned structure regulated by the Tennessee Safe Dams Program. Built in 1976, this earth dam stands at a hydraulic height of 20.9 feet and a structural height of 26.9 feet, with a total length of 410 feet. With a normal storage capacity of 63 acre-feet and a maximum storage of 99 acre-feet, Crystal serves as a critical component in managing water resources in the area, particularly for the Spring Creek watershed.

Despite its satisfactory condition assessment, Crystal poses a high hazard potential due to its location and design. The dam's spillway is uncontrolled, adding to the risk of potential flooding and necessitating regular inspections by the state regulatory agency. While the dam's emergency action plan status and risk assessment level are not currently specified, its role in water resource management underscores the importance of maintaining its structural integrity and readiness for any potential emergencies. Enthusiasts of water resources and climate will find the details of Crystal's design, operation, and regulatory oversight intriguing as they highlight the intersection of human infrastructure with natural ecosystems.
