Fogle Lake Dam, located in Ringgold County, Iowa, was completed in 1996 and stands at a height of 36 feet with a length of 810 feet. The dam serves primarily for recreational purposes, providing a surface area of 41.5 acres and a normal storage capacity of 378 acre-feet. Managed by the Iowa Department of Natural Resources, the dam is regulated, inspected, and enforced by state authorities, ensuring its safe operation and maintenance.

The dam's spillway, of uncontrolled type with a width of 2 feet, contributes to its significant hazard potential. However, the condition assessment conducted in June 2017 deemed the dam satisfactory, with a moderate risk rating. The dam is situated on TR- GRAND RIVER and has a drainage area of 0.85 square miles. Despite its hazard potential, the dam remains a popular spot for recreational activities within the community of Diagonal, Iowa.

As a focal point for outdoor enthusiasts and climate advocates, Fogle Lake Dam stands as a vital resource for water storage and recreation in the region. With its state-regulated operations and satisfactory condition, the dam continues to provide essential benefits while also warranting ongoing risk management measures to ensure the safety of surrounding communities and ecosystems.
