Frd No 36-a

About Frd No 36-a

The primary purpose of Frd No 36-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 Schrader Branch Caney River near Grenola.

The dam stands 56 feet tall and stretches 1,900 feet across, creates a reservoir covering 25 acres, has a maximum storage capacity of 2,489 acre-feet, and collects water from a drainage area of 4 square miles. Completed in 1972, 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 56 feet, this dam is taller than 94% of dams nationwide.
