Echo Dam
Echo Dam is an earth dam located in Summit County, Utah, built in 1931. It carries a High hazard potential classification.
About Echo Dam
The primary purpose of Echo 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 Bureau Of Reclamation (federal). It impounds the Weber River near Echo.
The dam stands 161 feet tall and stretches 1,887 feet across, creates a reservoir covering 1,455 acres, has a maximum storage capacity of 73,940 acre-feet, and collects water from a drainage area of 715 square miles. Completed in 1931, the structure is well-established, with more than 75 years of service.
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. An emergency action plan is in place for this dam. The most recent inspection on record was 07/07/2020.
At 161 feet, this dam is taller than 99% of all dams in the United States.
