Summary
The dam's primary purpose is for fire protection, stock, or as a small fish pond, with a storage capacity of 48 acre-feet. It stands at a height of 30 feet and stretches 226 feet in length, serving the TR-Point Creek in the Tulsa District.
Despite its small size, John Hankins Dam plays a crucial role in managing water resources in the region, especially for fire protection and livestock needs. The dam has not been rated for condition assessment, but it is classified as having a high risk potential. While it lacks a spillway, the dam's design and construction by the NRCS demonstrate a commitment to water management and conservation efforts in the area.
With its strategic location and purpose, John Hankins Dam serves as a testament to the importance of private initiatives in water resource management. As climate change continues to impact water availability, such structures are vital for ensuring the resilience of local communities and ecosystems. The dam's role in providing essential services underscores the need for ongoing monitoring and maintenance to safeguard its functionality and support sustainable water use in the region.

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.
