About Watkins Lake Dam
The primary purpose of Watkins 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 Hugh G Watkins (private). It impounds the Tr-lost Creek near Trenton.
The dam stands 26 feet tall, creates a reservoir covering 5 acres, has a maximum storage capacity of 70 acre-feet, and collects water from a drainage area of 90 square miles. Completed in 1972, 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.
