About Jasper Lake Dam
The primary purpose of Jasper 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 Arthur Jasper (private). It impounds the Tr-little Berger Creek near New Haven.
The dam stands 20 feet tall, creates a reservoir covering 6 acres, has a maximum storage capacity of 82 acre-feet, and collects water from a drainage area of 110 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.
