About Ler Sunset Debris Basin

The primary purpose of Ler Sunset Debris Basin is debris control. The dam is designed to catch sediment, rocks, and debris carried by flowing water — particularly important in areas prone to mudslides or heavy erosion. The dam is owned by Los Angeles County Department Of Public Works (local government). It impounds the Sunset Canyon near Burbank.

The dam stands 86 feet tall and stretches 379 feet across, creates a reservoir covering 2 acres, has a maximum storage capacity of 37 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1963, 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 12/01/2025.

At 86 feet, this dam is taller than 97% of all dams in the United States.
