Summary
The earth dam stands at a height of 37 feet, with a hydraulic height of 33 feet and a structural height of 37 feet. It spans a length of 1060 feet, providing a normal storage capacity of 123 acre-feet and a maximum storage of 720 acre-feet.
Despite its low hazard potential, the dam has a very high risk assessment rating due to its critical role in protecting the surrounding area from flooding. The controlled spillway, with a width of 1 foot, helps manage water flow during periods of high discharge. The dam is equipped with a valve outlet gate for controlled water release. While the dam's condition assessment is currently not rated, it undergoes inspections every 5 years to ensure its continued functionality and safety standards.
SCS-Caddo Creek Site-19 serves as an essential infrastructure for flood risk reduction in Carter County, Oklahoma, under the oversight of the state regulatory agency OWRB. As a key component of the region's water resource management, this dam plays a crucial role in safeguarding communities and properties from potential flood events. Its strategic location and design demonstrate a commitment to sustainable water management practices and climate resilience in the face of changing environmental 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.
