Coal Bank Watershed Cb-1

About Coal Bank Watershed Cb-1

The primary purpose of Coal Bank Watershed Cb-1 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 Natural Resources Conservation Service Area 2 (federal). It impounds the Coal Bank Draw near Eaton.

The dam stands 64 feet tall and stretches 2,544 feet across, creates a reservoir covering 139 acres, has a maximum storage capacity of 2,754 acre-feet, and collects water from a drainage area of 27 square miles. Completed in 1961, the structure is well into its service life at over 50 years old.

This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 08/30/2016.

At 64 feet, this dam is taller than 96% of all dams in the United States.
