Summary
Completed in 1975, this dam stands at a height of 26 feet with a hydraulic height of 23 feet and a length of 1560 feet. It has a storage capacity of 494 acre-feet and a normal storage of 74 acre-feet, serving as a vital infrastructure for managing water resources in Tillman County.
Managed by the Oklahoma Water Resources Board, the SCS-Jack Creek Site-7 has a low hazard potential and is rated as "Not Rated" in terms of condition assessment. Despite its risk assessment being very high, this dam has not been modified since its completion and is equipped with a controlled spillway and one outlet valve. The dam is inspected every 5 years, with the last inspection conducted in 1980, ensuring its operational integrity and compliance with state regulations for flood risk management.
With its location in a high-risk area for flooding, the SCS-Jack Creek Site-7 plays a crucial role in mitigating potential disasters and protecting the surrounding communities. As a key component of the water infrastructure in Tillman County, this dam is a testament to effective collaboration between state and federal agencies in safeguarding water resources and enhancing climate resilience 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.
