Summary
Completed in 1974, this dam stands at 36 feet high with a hydraulic height of 31 feet and a length of 2080 feet. It has a storage capacity of 2805 acre-feet and a normal storage of 804 acre-feet, serving as a crucial infrastructure for managing water resources in the region.
The dam features a controlled spillway and a valve outlet gate, with a low hazard potential and a very high risk assessment rating. Despite not being rated for condition assessment, SCS-Jack Creek Site-3 undergoes inspections every 5 years to ensure its structural integrity and functionality. The dam is operated and maintained by the state regulatory agency OWRB, and it plays a vital role in mitigating flood risks and protecting the surrounding area from potential water-related disasters.
Located in Tillman County, Oklahoma, this dam is a key component in the water resource management infrastructure of the region. With its strategic design and purposeful construction, SCS-Jack Creek Site-3 exemplifies the collaborative efforts of state and federal agencies in safeguarding the community against the impacts of climate variability and water-related hazards.

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.
