Summary
With a primary purpose of flood risk reduction, this dam stands at a height of 36 feet and has a storage capacity of 1,091 acre-feet. It is situated on TR East Cow Creek and is under the jurisdiction of the Oklahoma Water Resources Board (OWRB).
The dam features a controlled spillway and a single valve outlet gate for water release. Despite being classified as low hazard potential, the risk assessment for SCS-Cow Creek Site-12 is rated as very high (1). The condition of the dam is currently not rated, and it has not undergone any recent inspections since 1980. The surrounding area has a drainage area of 2.8 square miles, with a maximum discharge capacity of 432 cubic feet per second.
For water resource and climate enthusiasts, SCS-Cow Creek Site-12 presents an opportunity to study the management and regulation of dams in Oklahoma. Its location on TR East Cow Creek and the flood risk reduction purpose make it a critical infrastructure for mitigating potential disasters in the region. With a risk assessment indicating a very high level of risk, further assessments and inspections may be necessary to ensure the structural integrity and safety of this earth dam.

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.
