About Dd No 7

The primary purpose of Dd No 7 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 Switzler Creek Wd No 63 (local government). It impounds the Hoover Branch near Burlingame.

The dam stands 43 feet tall and stretches 2,100 feet across, creates a reservoir covering 34 acres, has a maximum storage capacity of 4,537 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1962, the structure is well into its service life at over 50 years old.

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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 08/28/2019.

At 43 feet, this dam is taller than 89% of dams nationwide.
