Summary
The dam stands at a height of 37 feet, with a hydraulic height of 31 feet and a structural height of 37 feet. It has a length of 500 feet and a storage capacity of 250 acre-feet, serving as a controlled spillway with one valve outlet gate.
Despite its age, Site-111 has a low hazard potential and has not been rated for condition assessment. The last inspection date was in 1980, with an inspection frequency of 5 years. The dam's risk assessment indicates a very high risk level, emphasizing the need for proper risk management measures to be put in place. With its critical role in flood risk reduction and water resource management in the region, continued monitoring and maintenance of SCS-Sandstone Creek Site-111 are essential to ensure its effectiveness and safety for the community.
Overall, SCS-Sandstone Creek Site-111 serves as a vital infrastructure for flood control along Sandstone Creek, providing essential protection for the surrounding area. With its historic significance and ongoing importance, the dam represents a key component of Oklahoma's water resource management efforts. As climate change continues to pose challenges to water infrastructure, the maintenance and upkeep of structures like Site-111 are crucial in safeguarding communities and ecosystems from the impacts of extreme weather events.

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.
