Summary
Constructed in 1978 by the USDA NRCS, this earth dam stands at a height of 45 feet and has a hydraulic height of 41 feet, providing storage of up to 586 acre-feet. Situated on the TR-Washita River, this dam plays a crucial role in managing water resources in the region and reducing the risk of flooding in the surrounding area.
With a low hazard potential and a very high risk assessment rating, the SCS-South Clinton Laterals Site-L15 is equipped with a controlled spillway and a single valve outlet gate. Despite not being rated for condition assessment, this dam has undergone inspections approximately every 5 years since its last inspection in 1980. The state of Oklahoma, through the OWRB, oversees the regulation, inspection, and enforcement of safety measures for this dam, ensuring its continued functionality and safety for the community of Parkerburg and the surrounding areas.
As an essential piece of infrastructure in managing water resources and mitigating flood risks, the SCS-South Clinton Laterals Site-L15 serves as a critical asset in the region's water management strategy. With its strategic location on the TR-Washita River and its effective flood risk reduction capabilities, this dam stands as a testament to the collaborative efforts of state and federal agencies in safeguarding communities and enhancing water resource resilience in Oklahoma.

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.
