Williams, a private dam located in Shelby, Tennessee, was completed in 1965 and stands at a hydraulic height of 14.9 feet with a structural height of 18.9 feet. The dam, primarily constructed of earth, serves the Big Creek Drainage Canal and has a normal storage capacity of 62 acre-feet. With a low hazard potential and a moderate risk assessment rating of 3, Williams has not been subject to a condition assessment and is currently deemed as "Not Rated."
While the dam has not been regulated or inspected by the state, it falls under the jurisdiction of the Memphis District of the US Army Corps of Engineers. Despite the lack of state oversight, Williams has a maximum storage capacity of 105 acre-feet, covering a surface area of 10.4 acres. The dam features an uncontrolled spillway and has not been modified in recent years. With no associated structures or outlet gates, Williams remains a key feature in the water resource management of the area.
Although no emergency action plan (EAP) has been prepared for Williams, the dam meets moderate risk management guidelines. As of the last inspection in December 2020, the dam's condition assessment remains unknown. With a designated inspection frequency of 5 years, Williams continues to play a crucial role in flood control and water resource management within the region, under the supervision of the Memphis District of the US Army Corps of Engineers.
