About Lake Arrowhead Dam
The primary purpose of Lake Arrowhead Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Arrow D Ranch Inc (private). It impounds the Tributary Of Black Bayou near Atlanta.
The dam stands 24 feet tall and stretches 1,000 feet across, creates a reservoir covering 83 acres, has a maximum storage capacity of 1,020 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1980, the structure is 46 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. An emergency action plan is in place for this dam. The most recent inspection on record was 08/08/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
