Summary
With a structural height of 32 feet and a hydraulic height of 26 feet, this dam boasts a storage capacity of 286 acre-feet and a spillway width of 1 foot. Despite its low hazard potential, the dam's risk assessment indicates a very high risk level, underscoring the importance of regular inspections and maintenance.
Managed by the Oklahoma Water Resources Board, the SCS-Chigley Sandy Creek Site-09 features a controlled spillway and a single valve outlet gate. While its condition assessment is currently not rated, the dam has undergone inspections every 5 years, with the last recorded inspection dating back to 1980. Even though the dam's emergency action plan status and risk management measures remain unspecified, the dam serves as a crucial infrastructure for flood control in the region, highlighting the intersection of water resource management and climate resilience in Oklahoma.
As climate change continues to impact water resources and weather patterns, the SCS-Chigley Sandy Creek Site-09 stands as a testament to the critical role of infrastructure in mitigating flood risks and safeguarding communities. With its state jurisdiction and regulatory oversight, the dam represents a collaborative effort between government agencies and designers to enhance water security in the face of evolving environmental challenges. As enthusiasts of water resources and climate adaptation, the SCS-Chigley Sandy Creek Site-09 serves as a compelling case study in sustainable dam management and resilience planning for a changing world.

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.
