About East Fork Clarks River Frs No 33
The primary purpose of East Fork Clarks River Frs No 33 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 Marshall County Conservation District (local government). It impounds the Clarks River near Shady Grove.
The dam stands 21 feet tall and stretches 950 feet across, creates a reservoir covering 17 acres, has a maximum storage capacity of 510 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1963, the structure is well into its service life at over 50 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. The most recent inspection on record was 06/26/2025.
