Summary
Completed in 1975, this earth dam stands at a height of 26 feet and has a hydraulic height of 23 feet, providing a storage capacity of 127 acre-feet. The dam spans a length of 530 feet and has a controlled spillway with a width of 1 foot.
With a low hazard potential and a very high risk assessment rating, SCS-Upper Elk Creek Site-06 is equipped with a single valve outlet gate for water control. Despite not being rated for its condition assessment, the dam undergoes inspections every 5 years, with the last inspection conducted in 1980. While the dam currently does not have an Emergency Action Plan (EAP) in place, it meets regulatory guidelines and has not experienced any major modifications since its completion.
Water resource and climate enthusiasts will find SCS-Upper Elk Creek Site-06 to be a fascinating example of flood risk reduction infrastructure in Oklahoma. Its design and construction by the USDA NRCS, along with its state-regulated status and low hazard potential, make it a noteworthy structure for those interested in water management and conservation efforts. The dam's storage capacity, spillway type, and risk assessment rating add to its significance in the realm of water resource protection and climate resilience.

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.
