Summary
This Earth-type dam stands at a height of 44 feet and has a hydraulic height of 40 feet, providing a storage capacity of 916 acre-feet with a normal storage level of 202 acre-feet. The dam spans a length of 1300 feet and has a spillway width of 2 feet, capable of handling a maximum discharge of 7302 cubic feet per second.
Despite being assessed as in fair condition during the last inspection in July 2011, this Significant hazard potential dam remains at risk due to its Very High risk assessment rating. The dam is equipped with a single valve outlet gate and is inspected every 3 years. The state of Oklahoma's OWRB is responsible for permitting, inspecting, and enforcing regulations for this dam, ensuring its continued safe operation for flood risk management in the area. Water resource and climate enthusiasts will find SCS-Timber Creek Site-6 to be a noteworthy infrastructure contributing to water management efforts in Oklahoma's watershed.

Dam Data Reference
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.
