Hendley Lake Dam is an earth dam located in Stoddard County, Missouri, built in 1968. It carries a High hazard potential classification.
About Hendley Lake Dam
The primary purpose of Hendley Lake Dam 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 Joe H Hendley (private). It impounds the Tr-castor River near Clines Island.
The dam stands 14 feet tall, creates a reservoir covering 11 acres, has a maximum storage capacity of 82 acre-feet, and collects water from a drainage area of 335 square miles. Completed in 1968, 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.

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. The Missouri dam safety program can provide more specific information about emergency planning for this structure.
