Scs-South Clinton Laterals Site-L11 dam
Scs-South Clinton Laterals Site-L11
The SCS-South Clinton Laterals Site-L11 is a state-owned flood risk reduction dam located in Washita County, Oklahoma, near the town of Parkersburg. Built in 1969 by the USDA NRCS, the dam serves the primary purpose of mitigating flooding along the TO-Washita River. With a height of 27 feet and a length of 3800 feet, the earth dam has a storage capacity of 249 acre-feet and a normal storage level of 83 acre-feet.
Although the dam has a low hazard potential, it is classified as having a very high risk due to its condition assessment not being rated. The structure features a controlled spillway and a single valve outlet gate. Despite its age, the dam has not been inspected since 1980 and is due for a reassessment as part of its mandated 5-year inspection frequency. The SCS-South Clinton Laterals Site-L11 is under the jurisdiction of the Oklahoma Water Resources Board and is regulated, permitted, inspected, and enforced by the state regulatory agency.
Water resource and climate enthusiasts interested in the management and maintenance of flood control infrastructure will find the SCS-South Clinton Laterals Site-L11 to be a fascinating case study. The dam's location along the TO-Washita River in a high-risk area highlights the importance of regular inspections and upkeep to ensure public safety and prevent potential disasters. As the dam approaches its 50th anniversary, stakeholders may advocate for updated risk assessments and emergency action plans to address the evolving environmental conditions and potential hazards.
Dam data reference
Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Scs-South Clinton Laterals Site-L11
Where does the data for Scs-South Clinton Laterals Site-L11 come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
