About Basin 2

The primary purpose of Basin 2 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 Yoe Borough (local government). It impounds the Mill Creek.

The dam stands 10 feet tall and stretches 160 feet across, has a maximum storage capacity of 4 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1998, the structure is 28 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 12/29/2020.
