About Farmer Lake Dam

The primary purpose of Farmer Lake 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 Caswell County (local government). It impounds the Country Line Creek near Milton.

The dam stands 77 feet tall and stretches 1,340 feet across, creates a reservoir covering 390 acres, has a maximum storage capacity of 15,268 acre-feet, and collects water from a drainage area of 46 square miles. Completed in 1983, the structure is 43 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 02/25/2025.

At 77 feet, this dam is taller than 97% of all dams in the United States.
