Summary
Managed by the Natural Resources Conservation Service, this earth dam stands at a height of 19 feet with a hydraulic height of 16 feet, providing a storage capacity of 87 acre-feet. While the dam has a low hazard potential and is currently deemed to be in "Not Rated" condition, its risk assessment is moderate.
The dam features an uncontrolled spillway and outlet gates, with no associated locks or lock dimensions listed. With a length of 315 feet and a surface area of 9 acres, Henderson Lake Dam provides a serene setting for outdoor activities and water recreation. While the dam has not been modified in recent years and lacks certain inspection and emergency preparedness measures, it continues to serve as a valuable resource for the local community.
Enthusiasts interested in water resource management and climate resilience may appreciate the ecological and recreational value that Henderson Lake Dam provides to the region. With its modest size and low hazard potential, the dam represents a balance between human enjoyment of water resources and the need for safety and risk management in dam infrastructure. As climate change impacts become more pronounced, the importance of maintaining and monitoring dams like Henderson Lake Dam will be crucial in ensuring the safety and sustainability of our water resources for future generations.

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.
