About Lake Gallimore Dam
The primary purpose of Lake Gallimore Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Dod Usn (federal). It impounds the Boggs Creek near Loogootee.
The dam stands 26 feet tall and stretches 890 feet across, creates a reservoir covering 102 acres, has a maximum storage capacity of 6,740 acre-feet, and collects water from a drainage area of 41 square miles. Completed in 1962, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam.
