Mississippi River Lock and Dam 2, also known as Pool 2, is a federal structure located in Hastings, Minnesota. Completed in 1931, this concrete dam serves primarily for navigation purposes on the Mississippi River. With a height of 23 feet and a length of 4250 feet, the dam has a significant storage capacity of 787,000 acre-feet and can discharge up to 171,000 cubic feet per second through its controlled spillway.

Managed by the US Army Corps of Engineers, Mississippi River Lock and Dam 2 poses a significant hazard potential, with a very high risk assessment rating. However, the Corps actively mitigates these risks by continuously monitoring the dam's condition, engaging with emergency managers, and updating its emergency action plan. The dam plays a vital role in managing water levels and mitigating flood risks, but severe weather events can still pose challenges, requiring careful management and coordination to ensure the dam's structural integrity and downstream safety.

Overall, Mississippi River Lock and Dam 2 stands as a crucial piece of infrastructure in the region, balancing the needs of navigation, flood control, and water management. The ongoing efforts of the US Army Corps of Engineers ensure that the dam remains a reliable and safe structure, ready to respond to any potential emergencies that may arise.
