About Sullwold Dam
The primary purpose of Sullwold 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 Corliss Sullwold & Christa Britton (private). It impounds the Tr-turkey Creek.
The dam stands 9 feet tall and stretches 276 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 89 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1960, the structure is well into its service life at over 50 years old.
