Summary
The dam stands at a height of 29 feet with a hydraulic height of 25 feet and a length of 1160 feet, providing a storage capacity of 462 acre-feet. Despite being last inspected in 1980, the dam's hazard potential is rated as low, with a very high risk assessment indicating the need for proactive risk management measures.
Located in HERRING, Oklahoma, the SCS-Sandstone Creek Site-021 dam is primarily maintained for flood risk reduction purposes by the Natural Resources Conservation Service. With a controlled spillway and a single valve outlet gate, the dam has a surface area of 19 acres and a normal storage capacity of 150 acre-feet. While the condition assessment is currently not rated, the dam's risk profile is classified as very high (1), highlighting the importance of regular inspections and emergency action planning to ensure the safety and integrity of the structure.
Managed by the OWRB and falling under the jurisdiction of the state of Oklahoma, the SCS-Sandstone Creek Site-021 dam serves as a vital infrastructure for water resource management in the region. With a congressional representative of Frank D. Lucas (R) and oversight from the Tulsa District of the USACE, the dam's role in mitigating flood risks along TR-Sandstone Creek underscores the critical importance of sustainable water resource management practices in the face of evolving climate challenges.

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.
