Summary
With a hydraulic height of 26 feet and a structural height of 32 feet, this dam spans 1375 feet and has a storage capacity of 870 acre-feet. The dam's fair condition assessment and high hazard potential highlight the importance of regular inspections and risk management measures to ensure its structural integrity and the safety of surrounding areas.
The dam features a controlled spillway and a slide (sluice gate) outlet gate to manage water flow, with a maximum discharge capacity of 14,938 cubic feet per second. Despite its relatively small surface area of 16 acres, the dam plays a crucial role in protecting the local community from potential flooding events. The regulatory oversight by the Oklahoma Water Resources Board (OWRB) ensures that the dam meets state permitting, inspection, and enforcement requirements, emphasizing the collaborative efforts between state agencies and the USDA NRCS in managing water resources and climate-related risks in the region.
The risk assessment for SCS-Little Deep Fork Creek Site-33 categorizes it as having a very high risk level, underscoring the need for proactive emergency action planning and adherence to established guidelines. As the dam is situated in an area with a high hazard potential, continuous monitoring, maintenance, and potential modifications are essential to mitigate risks and safeguard the community from potential inundation events. The data updated in May 2021 highlights the ongoing commitment to ensuring the safety and effectiveness of this critical infrastructure in managing water resources and climate impacts in Oklahoma.

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.
