Summary
Standing at 30 feet tall and 700 feet long, this dam serves multiple purposes, with a primary purpose categorized as "Other." The dam has a storage capacity of 300 acre-feet, with a normal storage level of 77 acre-feet and a surface area of 13 acres. The dam is located along the TR-WASHITA RIV, under the jurisdiction of the OWRB.
Despite being rated as having a low hazard potential, the SCS-South Clinton Laterals Site-L14 is considered to have a very high risk level, with a DSAC risk rating of 1. The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. The last inspection date for this dam was in 1980, with an inspection frequency of 5 years. The condition assessment for the dam is listed as "Not Rated," and there is no information available regarding the preparation of an Emergency Action Plan (EAP) or the existence of inundation maps.
Water resource and climate enthusiasts are drawn to the SCS-South Clinton Laterals Site-L14 for its unique design and purpose, as well as the risk factors associated with its location and structure. As a state-regulated dam in Oklahoma, this site serves as an important water management tool along the TR-WASHITA RIV. With a focus on risk management and ensuring the safety of surrounding areas, ongoing inspections and assessments are crucial for the continued operation of this earth dam.

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.
