Summary
The dam sits on the TR-CANADIAN SANDY CR and has a maximum storage capacity of 462 acre-feet, with a normal storage of 30 acre-feet. With a low hazard potential and a very high risk assessment rating, this dam is inspected every 5 years to ensure its structural integrity and safety.
Located in Pontotoc County, near the city of VANOSS, the SCS-Sandy Creek Site-09 dam is managed by the OWRB and falls under the jurisdiction of the state of Oklahoma. Despite its relatively small surface area of 8 acres, the dam plays a crucial role in managing water resources in the area, with a drainage area of 1.1 square miles and a maximum discharge capacity of 477 cubic feet per second. The dam features a controlled spillway and a single valve outlet gate for water release.
With a design height of 31 feet and a length of 940 feet, the SCS-Sandy Creek Site-09 dam is a vital infrastructure that not only contributes to water resource management but also serves as a testament to the collaborative efforts of state and federal agencies in ensuring the safety and sustainability of water structures in Oklahoma. As climate change continues to impact water resources, the importance of maintaining and monitoring dams like SCS-Sandy Creek Site-09 becomes increasingly crucial for the resilience of communities and ecosystems in the region.

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.
