Abiaca Watershed Structure Y-34-06 Dam

About Abiaca Watershed Structure Y-34-06 Dam

The primary purpose of Abiaca Watershed Structure Y-34-06 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 Abiaca Watershed District (local government). It impounds the Coila Creek near Sidon Off To The West.

The dam stands 41 feet tall and stretches 1,993 feet across, creates a reservoir covering 83 acres, has a maximum storage capacity of 6,305 acre-feet, and collects water from a drainage area of 14 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 06/17/2021.

At 41 feet, this dam is taller than 88% of dams nationwide.
