Completed in 1970 by the US Army Corps of Engineers, this gravity dam serves multiple purposes, including hydroelectric power generation, navigation, and recreation. With a hydraulic height of 55 feet and a structural height of 100 feet, the dam plays a crucial role in managing water levels and mitigating flood risks in the region.

The dam, with a length of 1167 feet and a storage capacity of 331,800 acre-feet, provides vital flood control measures and recreational opportunities for visitors. Despite its significant hazard potential, the US Army Corps of Engineers employs various risk management measures to ensure the dam's structural integrity and public safety. This includes regular inspections, maintenance activities, and collaboration with local emergency managers to develop emergency action plans and raise public awareness about the dam's functions and potential risks.

Millers Ferry Lock and Dam is a key infrastructure asset in Alabama's water resource management system, demonstrating the importance of sustainable dam operations in the face of climate variability and extreme weather events. As water resource and climate enthusiasts, understanding the role of this dam in flood risk management and recreational activities can provide valuable insights into the interconnected relationship between water resources, infrastructure, and environmental stewardship in the region.
