Otter is a privately owned dam located on the Loosahatchie River in Shelby, Tennessee, near the city of Memphis. Built in 1954, this earth dam stands at a height of 19.5 feet with a hydraulic height of 15.5 feet. It has a storage capacity of 160 acre-feet and serves a primary purpose that is not specified in the data. The dam is regulated by the Tennessee Safe Dams Program and undergoes regular inspections, with the last one conducted in July 2020.

With a high hazard potential and a moderate risk assessment rating, Otter poses a significant risk to the surrounding area in the event of a failure. Despite its condition being labeled as "Not Rated", the dam has not been assessed for its current state. There is no Emergency Action Plan (EAP) in place, and it is unclear if the dam meets guidelines for such preparedness. The lack of inundation maps and risk management measures further highlight the need for increased attention to the safety and maintenance of Otter.

For water resource and climate enthusiasts, Otter presents a case study in the importance of proactive dam management and emergency preparedness. With its location in a populated area and the potential for significant consequences in the event of a breach, it is crucial for the owners and regulators to prioritize regular inspections, condition assessments, and the development of an effective EAP. By addressing the identified risks and implementing necessary measures, the safety and resilience of Otter can be enhanced, ensuring the protection of both the dam infrastructure and the communities downstream.
