Completed in 1991 by the US Army Corps of Engineers, this gravity dam serves primarily for navigation purposes but also supports recreation and water supply. With a hydraulic height of 63 feet and a structural height of 134 feet, the dam spans 866 feet in length and has a storage capacity of 108,500 acre-feet.
This significant dam, with a spillway width of 360 feet and controlled spillway type, plays a crucial role in managing water levels and mitigating flood risks in the region. Despite its very high risk assessment rating, the USACE actively monitors and maintains the dam to ensure its structural integrity and reduce potential hazards. Emergency action plans are regularly updated, and risk management measures are in place to engage with local authorities and the public, emphasizing preparedness and response in case of dam-related emergencies.
In light of its importance for water resource management and flood control, the Red River Lock and Dam 3 stands as a vital infrastructure project managed by the US Army Corps of Engineers. As climate change continues to impact water systems, the ongoing monitoring and maintenance of this dam are essential to safeguarding the surrounding communities and ensuring the sustainable use of this critical water resource.
