About Eftink Lake Dam
The primary purpose of Eftink 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 George Eftink (private). It impounds the Tr-caney Creek near Oran.
The dam stands 25 feet tall, creates a reservoir covering 19 acres, has a maximum storage capacity of 254 acre-feet, and collects water from a drainage area of 200 square miles. Completed in 1971, 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.
