About Fordyce Lake Dam
The primary purpose of Fordyce Lake 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 Max Fordyce (private). It impounds the Tr-trail Creek near Mount Moriah.
The dam stands 32 feet tall, creates a reservoir covering 3 acres, has a maximum storage capacity of 51 acre-feet, and collects water from a drainage area of 90 square miles. Completed in 1974, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
At 32 feet, this dam is taller than 76% of dams nationwide.
