Summary
Built in 1975 by USDA NRCS, this earth dam stands at 28 feet high and serves the primary purpose of flood risk reduction. With a storage capacity of 957 acre-feet and a normal storage of 252 acre-feet, this dam covers a surface area of 31 acres and has a controlled spillway with a width of 2 feet.
Despite being classified as low hazard potential, the risk assessment for SCS-Jack Creek Site-2a indicates a very high risk level (1). The dam, under the jurisdiction of the Oklahoma Water Resources Board, has not been rated for its condition assessment and was last inspected in 1980. It is equipped with a valve outlet gate and is subject to inspection every 5 years. The dam has not undergone modifications since its completion and does not have an emergency action plan in place.
Enthusiasts of water resources and climate in the Tillman County area may find SCS-Jack Creek Site-2a an intriguing structure to study due to its historical significance, design details, and risk assessment. As a key flood risk reduction asset in the region, understanding the operational and regulatory aspects of this dam can provide valuable insights into water management practices and the challenges of maintaining aging infrastructure in the face of changing climatic conditions.

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.
