Mississippi River Locks and Dam 15, also known as Pool 15, is a federal-owned structure located in Scott County, Iowa. Completed in 1934, this concrete gravity dam serves primarily for navigation purposes on the Mississippi River. With a hydraulic height of 16 feet and a structural height of 41 feet, the dam spans 1606 feet in length and has a storage capacity of 30,000 acre-feet.

The dam features a controlled spillway with a width of 1203 feet and includes two locks, each measuring 600 feet in length and 110 feet in width. Despite its significant hazard potential, the dam is equipped with an emergency action plan, regularly updated by the US Army Corps of Engineers, to manage flood risks associated with the structure. Through continuous monitoring, maintenance, and collaboration with local emergency managers, the USACE works diligently to ensure the structural integrity of the dam and mitigate potential risks to surrounding areas.

As a critical infrastructure on the Mississippi River, Locks and Dam 15 plays a vital role in regulating water levels and facilitating navigation along the waterway. With a comprehensive risk management approach in place, including regular inspections, emergency preparedness, and public outreach, the dam serves as a testament to the importance of proactive measures in safeguarding water resources and addressing climate-related challenges in the region.
