About Busseron Dam No. A-4
The primary purpose of Busseron Dam No. A-4 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 Busseron Conservancy District (local government). It impounds the Unnamed Tributary Middle Fork Creek near Carlisle.
The dam stands 22 feet tall and stretches 1,070 feet across, creates a reservoir covering 14 acres, has a maximum storage capacity of 372 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1967, 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.
