Summary
Standing at 14 feet in height with a storage capacity of 82 acre-feet, the dam also provides debris control, fire protection, and serves as a recreational area for locals. With a hazard potential rated as high, the dam's condition assessment is currently not rated, highlighting the urgency for regular inspections and maintenance.
Managed by private owners, Hendley Lake Dam plays a crucial role in protecting the Stoddard County community from potential flooding events. Despite being non-regulated by the state, the dam's significance in flood risk reduction, coupled with its location and design as an earth dam with buttress core types, underscores the importance of proper maintenance and emergency preparedness. As climate change continues to impact water resources, enthusiasts can appreciate the strategic placement and purpose of Hendley Lake Dam in safeguarding the local ecosystem and community.
For water resource and climate enthusiasts, understanding the operational details and purpose of structures like Hendley Lake Dam is essential in advocating for sustainable water management practices. With a primary goal of flood risk reduction and additional functions such as stock pond usage, the dam's role in preserving water quality, supporting wildlife habitats, and ensuring community safety is evident. As discussions around climate resilience and water security gain momentum, Hendley Lake Dam stands as a testament to the intricate balance between human needs and environmental stewardship in the face of changing weather patterns.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
