Summary
The dam stands at a height of 30 feet and has a hydraulic height of 13 feet, with a capacity of 60 acre-feet. It spans a length of 220 feet and is primarily made of earth and stone materials with a soil foundation, regulated by the Oklahoma Water Resources Board.
Despite its low hazard potential and lack of a condition assessment rating, Hunnicutt poses a very high risk due to its location on TR-Little Deep Creek. The dam features a controlled spillway and one outlet valve, with a maximum discharge capacity of 1740 cubic feet per second. While it has not been modified in recent years, the dam is subject to regular inspections and falls under state jurisdiction for permitting, inspection, and enforcement.
For water resource and climate enthusiasts, Hunnicutt serves as a notable structure in Custer County, Oklahoma, showcasing the engineering and regulatory aspects of dam infrastructure in the region. Its risk profile highlights the importance of monitoring and maintaining such structures to ensure public safety and environmental protection along the TR-Little Deep Creek watershed.

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.
