Lake Ahquabi Dam, located in Warren County, Iowa, was completed in 1935 and is owned by the state. The dam stands at 43 feet tall and spans a length of 1020 feet, holding a maximum storage capacity of 2395 acre-feet. With its primary purpose being recreation, the dam creates a surface area of 113 acres and is situated on TR-Squaw Creek, a tributary of the Red Rock Reservoir.

Managed by the Iowa Department of Natural Resources, the dam is regulated, permitted, inspected, and enforced by the state. Although its hazard potential is classified as significant, the dam's condition assessment is fair as of May 2019. While it poses a moderate risk, there are no emergency action plans in place, and the last inspection took place in May 2019. The spillway, with a width of 30 feet, is uncontrolled, allowing for the controlled release of excess water to prevent overflow.

Lake Ahquabi Dam serves as a vital recreational area in Iowa, offering opportunities for boating, fishing, and other water-related activities. With its scenic location and significant storage capacity, the dam plays a crucial role in water resource management and climate resilience efforts in the region. While the dam's risk assessment indicates moderate potential, ongoing monitoring and maintenance ensure the safety and integrity of this essential water infrastructure.
