Summary
This 63-foot tall structure provides a maximum storage capacity of 3208 acre-feet and a normal storage of 241 acre-feet across a surface area of 35 acres. With a controlled spillway and a low hazard potential, the dam has a very high risk assessment rating, indicating the importance of its maintenance and inspection protocols.
The dam features a stone core and a soil foundation, with a single valve outlet gate for water management. Despite its last inspection date in 1980, the structure is not currently rated for its condition assessment. While it meets state jurisdiction, permitting, inspection, and enforcement requirements, the dam lacks updated emergency action plans and inundation maps. The risk management measures and potential hazards associated with the dam should be carefully monitored and addressed to ensure the safety of downstream communities and the integrity of the water resource infrastructure.
Located in the Tulsa District, SCS-Sandy Creek Site-04 serves as a critical flood control structure in the region under the oversight of the OWRB. As climate change continues to impact water resources, the importance of maintaining and updating infrastructure like this dam becomes increasingly vital. Collaboration between state and federal agencies, as well as regular monitoring and assessment of the dam's condition and risk factors, will be essential in safeguarding the surrounding area from potential flooding events and ensuring the long-term resilience of the water resource system.

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.
