Summary
With a height of 21 feet and a length of 1540 feet, this dam has a storage capacity of 332 acre-feet and a maximum discharge of 1720 cubic feet per second. The dam features a controlled spillway and a single valve outlet gate, with a hazard potential rated as low and a condition assessment not yet rated.
Managed by the Oklahoma Water Resources Board, this site has not been inspected since 1980 and has an inspection frequency of 5 years. Despite its low hazard potential, the risk assessment for this dam is very high, emphasizing the need for regular maintenance and monitoring. While the dam serves its primary purpose of flood risk reduction effectively, there is room for improvement in terms of condition assessment and emergency action planning to mitigate potential risks associated with high-risk events. For water resource and climate enthusiasts, the SCS-Little Deep Fork Creek Site-09 offers a fascinating case study in dam management and risk assessment within the state of Oklahoma.

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.
