Scs-Little Washita River Site-42 dam
Scs-Little Washita River Site-42
SCS-Little Washita River Site-42, located in Ninnekah, Oklahoma, is a state-regulated dam designed by the USDA NRCS for flood risk reduction on the TR-East Bills Creek. Completed in 1969, this earthen dam stands at a height of 26 feet and spans a length of 715 feet. With a normal storage capacity of 35 acre-feet and a maximum discharge of 310 cubic feet per second, this dam serves as a crucial infrastructure for managing water resources in the area.
Despite being rated as having a low hazard potential, the risk assessment for SCS-Little Washita River Site-42 indicates a very high risk level, emphasizing the importance of regular inspections and maintenance. The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. While the condition assessment is currently not rated, the dam's emergency action plan and risk management measures are not specified, highlighting the need for further evaluation and preparedness in case of emergencies.
With the Tulsa District overseeing its regulation and the OWRB as the state regulatory agency, SCS-Little Washita River Site-42 plays a crucial role in mitigating flood risks and ensuring water resource management in the Grady County area. As water resource and climate enthusiasts, understanding the infrastructure and maintenance of such dams is essential for promoting sustainable practices and protecting communities from potential hazards related to water management.
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-Little Washita River Site-42
Where does the data for Scs-Little Washita River Site-42 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.
