Mississippi River Lock and Dam 10, located in Guttenberg, Iowa, is a vital water resource structure managed by the US Army Corps of Engineers. Completed in 1937, this concrete dam stands at 20 feet high with a hydraulic height of 33 feet and a structural height of 43 feet. The dam serves the primary purpose of navigation on the Mississippi River, with recreational activities also supported in the area.

Lock & Dam 10 features a controlled spillway that regulates the water level for navigation purposes, with a maximum discharge capacity of 308,000 cubic feet per second. Despite being classified as a significant hazard potential structure, the risk assessment conducted in 2015 deemed it a low-risk dam due to ongoing risk management measures implemented by USACE. Regular maintenance and repairs are conducted to ensure the dam's functionality and to address potential risks such as aging infrastructure and navigation accidents.

USACE remains committed to reducing risks associated with Lock & Dam 10, engaging with the public to raise awareness and coordinating with emergency managers during flood events. With a focus on safety and effective risk management, this dam continues to play a crucial role in maintaining river traffic while safeguarding the surrounding environment and communities.
