About Dam No 2-6 (timber Hill Lake)
The primary purpose of Dam No 2-6 (timber Hill Lake) 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 Twin Caney Wjd No 34 (local government). It impounds the Otter Creek near Caney.
The dam stands 59 feet tall and stretches 1,400 feet across, creates a reservoir covering 90 acres, has a maximum storage capacity of 3,520 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1966, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 01/03/2024.
At 59 feet, this dam is taller than 95% of all dams in the United States.
