Mississippi River Lock and Dam 7, also known as Pool 7, is a federal-owned structure located in La Crescent, Minnesota. Completed in 1937, it serves primarily for navigation purposes along the Mississippi River. With a concrete dam type, Lock and Dam 7 has a hydraulic height of 25 feet and a structural height of 41 feet, providing a controlled spillway to maintain a constant pool level for river traffic at elevation 638.5.

The risk assessment for Lock and Dam 7 in 2018 identified it as a low-risk dam among over 700 dams managed by the US Army Corps of Engineers. Risks are primarily associated with aging miter gates in the locks and potential navigation accidents. To mitigate these risks, USACE continuously monitors and maintains the dam, prioritizing activities that reduce potential hazards. Additionally, public engagement and coordination with state and county emergency managers help raise awareness of dam-related risks and ensure public safety, particularly during river flood events.

Overall, Lock and Dam 7 plays a crucial role in maintaining navigational access along the Mississippi River, with USACE implementing risk management measures to safeguard public safety and reduce potential hazards associated with the dam. Despite identified risks, ongoing maintenance and proactive measures aim to ensure the continued functionality and safety of this important water resource infrastructure.
