Summary

Completed in 1970, this dam stands at a height of 50 feet and has a storage capacity of 3,449 acre-feet. With a significant hazard potential and a fair condition assessment, this dam plays a crucial role in managing water resources in the region.

Managed by the Oklahoma Water Resources Board, SCS-Caddo Creek Site-28 is regulated, permitted, inspected, and enforced by the state, ensuring its structural integrity and safety. With a controlled spillway, one valve outlet gate, and a maximum discharge capacity of 8,800 cubic feet per second, this dam is equipped to handle high-risk scenarios efficiently. The surrounding area, covering 26 acres with a drainage area of 8.27 square miles, benefits from the flood protection and water storage provided by this essential infrastructure.

As a key component in the water management system of the region, SCS-Caddo Creek Site-28 is vital in safeguarding against floods and ensuring water resource sustainability. Its very high risk assessment rating underscores the importance of ongoing monitoring and maintenance to uphold its functionality and protect downstream communities. With a rich history of service since its completion, this dam remains an integral part of the local water infrastructure, reflecting the dedication to climate resilience and resource conservation.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
