About Lake Armistead
The primary purpose of Lake Armistead 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 Swfwmd (local government). It impounds the Lake Armistead/rocky Creek near Citrus Park.
The dam stands 7 feet tall and stretches 35 feet across, creates a reservoir covering 33 acres, and has a maximum storage capacity of 6,000 acre-feet. Completed in 1972, 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.
