About Pemberton Lake Dam-sec 22
The primary purpose of Pemberton Lake Dam-sec 22 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 Don Pemberton (private). It impounds the Tr-headwater Diversion Channl near Dutchtown.
The dam stands 30 feet tall, creates a reservoir covering 5 acres, has a maximum storage capacity of 80 acre-feet, and collects water from a drainage area of 50 square miles. Completed in 1971, 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.
