About Echo Lake
The primary purpose of Echo 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 Bpl, Doacf/state Of Maine (state). It impounds the Arnold Brook.
The dam stands 17 feet tall and stretches 154 feet across, creates a reservoir covering 83 acres, has a maximum storage capacity of 257 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1963, 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 08/01/2014.
