Summary
The dam stands at a height of 26 feet with a hydraulic height of 20 feet and a length of 1560 feet, providing a storage capacity of 117 acre-feet. Despite being categorized as low hazard potential, the risk assessment indicates a very high risk level, emphasizing the importance of regular inspections and maintenance to ensure public safety.
Managed by the Oklahoma Water Resources Board (OWRB), this dam features a controlled spillway and a single valve outlet gate. While the condition assessment currently remains unrated, the dam has not undergone any modifications since its construction. The site falls under the jurisdiction of the state regulatory agency and undergoes regular inspections, enforcement, and permitting to ensure compliance with safety standards. With a congressman representative of Tom Cole (R), the dam serves as a crucial infrastructure for flood control in Murray County, Oklahoma, highlighting the collaboration between state and federal agencies in managing water resources in the region.
In the realm of water resource and climate management, SCS-Chigley Sandy Creek Site-11 presents an intriguing case study of a state-maintained earth dam designed for flood risk reduction. The site's historical significance dates back to 1955, showcasing early efforts in water infrastructure development to mitigate the impacts of natural disasters in the region. With a focus on safety and risk management, this dam serves as a vital component of the local watershed, requiring ongoing monitoring and assessment to address potential hazards and ensure the resilience of the surrounding communities.

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.
