Frd No 41-a

About Frd No 41-a

The primary purpose of Frd No 41-a 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 Big Caney Wjd No 31 (local government). It impounds the Corum Creek near Grenola.

The dam stands 37 feet tall and stretches 2,200 feet across, creates a reservoir covering 34 acres, has a maximum storage capacity of 3,097 acre-feet, and collects water from a drainage area of 7 square miles. Completed in 1968, the structure is well into its service life at over 50 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in 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 03/24/2021.

At 37 feet, this dam is taller than 84% of dams nationwide.
