About Hitz Lake Dam
The primary purpose of Hitz 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 Walter Hitz (private). It impounds the Tr-mccoy Creek near Chain Of Rocks.
The dam stands 25 feet tall, creates a reservoir covering 8 acres, has a maximum storage capacity of 107 acre-feet, and collects water from a drainage area of 130 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.
