About Hackberry Draw Site No. 2 Dam
The primary purpose of Hackberry Draw Site No. 2 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 Hackberry Draw Watershed District (local government). It impounds the Hackberry Draw near Happy Valley, Carlsbad.
The dam stands 46 feet tall and stretches 1,663 feet across, creates a reservoir covering 30 acres, has a maximum storage capacity of 320 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1967, 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 01/28/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.
At 46 feet, this dam is taller than 91% of dams nationwide.
