Summary
With a dam height of 26 feet and a storage capacity of 181 acre-feet, this structure plays a crucial role in managing water resources in the region. The dam's primary purpose is flood risk reduction, and it is inspected every 5 years with a low hazard potential rating.
Despite its age, SCS-Sandstone Creek Site-117 remains in good condition, with a very high risk assessment rating of 1. The dam features a controlled spillway and a single valve outlet gate for water release. While it has not been modified in recent years, the dam is equipped to handle a maximum discharge of 1,215 cubic feet per second. The surrounding area covers 22 acres and serves as a vital asset for water resource management in the region.
With the Oklahoma Water Resources Board overseeing state jurisdiction and regulatory aspects of the dam, SCS-Sandstone Creek Site-117 stands as a testament to effective collaboration between government agencies and the USDA NRCS in safeguarding the local community against potential flood risks. For water resource and climate enthusiasts, this site offers a prime example of sustainable infrastructure development and management in ensuring the safety and well-being of communities in flood-prone areas.

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.
