Summary
The dam, completed in 1963, stands at a height of 23.3 feet and stretches 850 feet in length. With a storage capacity of 1616 acre-feet and a normal storage level of 821.1 feet, the dam impounds water from Mill Branch, creating a surface area of 50 acres for recreational activities.
Managed by the Natural Resources Conservation Service, Hendricks Lake Dam has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. Despite not being state regulated, the dam undergoes regular inspections with a frequency of 5 years to ensure its structural integrity and safety. In the event of emergencies, however, details on emergency action plans and inundation maps are currently not available, indicating room for improvement in risk management and preparedness.
Climate and water resource enthusiasts may find Hendricks Lake Dam an interesting case study for examining the balance between recreational benefits and potential risks associated with privately owned dams. The moderate risk assessment rating and lack of comprehensive emergency preparedness measures highlight the importance of proactive risk management strategies to ensure the safety and sustainability of such water infrastructure in the face of changing environmental conditions.

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.
