Summary

Completed in 1955, this dam stands at a height of 42 feet and has a hydraulic height of 35 feet, providing a storage capacity of 2925 acre-feet for normal operations. With a drainage area of 6385 acres and a maximum discharge capability of 31506 cubic feet per second, this dam plays a crucial role in managing water flow in the region.

Despite its fair condition assessment and high hazard potential, SCS-Double Creek Site-1 has been regulated, permitted, inspected, and enforced by the Oklahoma Water Resources Board. With a controlled spillway type and a single valve outlet gate, this dam ensures effective flood risk reduction measures for the surrounding area. While it has not been modified in recent years and lacks certain emergency preparedness features, the dam's risk assessment indicates a very high level of risk, highlighting the need for continued monitoring and maintenance to safeguard against potential hazards and ensure the safety of the community.

As a key infrastructure for water resource management in Washington County, Oklahoma, SCS-Double Creek Site-1 serves as a vital asset for mitigating flood risks and protecting the local environment. With its stone core and soil foundation, this dam exemplifies the importance of sustainable engineering practices in creating resilient water infrastructure. Climate and water resource enthusiasts can appreciate the intricate design and operational details of this dam as it continues to play a crucial role in safeguarding against water-related risks in the region.

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.
