North Ponding Dam

About North Ponding Dam

The primary purpose of North Ponding 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 City Of Holbrook (local government). It impounds the Unnamed To The Lcr near Holbrook.

The dam stands 8 feet tall and stretches 5,088 feet across, creates a reservoir covering 81 acres, and has a storage capacity of 303 acre-feet. Completed in 1977, the structure is 49 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 05/23/2024.
