Scs-Big Wewoka Creek Site-23 dam
Scs-Big Wewoka Creek Site-23
SCS-Big Wewoka Creek Site-23 is a state-regulated earth dam located in Wewoka, Oklahoma, designed by the USDA NRCS. Completed in 1958, this dam serves the primary purpose of flood risk reduction along TR-COON CREEK. With a height of 24 feet and a length of 1150 feet, the dam has a storage capacity of 733 acre-feet and a maximum discharge of 2700 cubic feet per second. Despite its low hazard potential, the risk assessment for this dam is rated as very high, emphasizing the importance of proper risk management measures.
Managed by the Oklahoma Water Resources Board, SCS-Big Wewoka Creek Site-23 has a controlled spillway and a single valve outlet gate. The dam's condition assessment is currently not rated, with the last inspection conducted in 1980. Although the dam meets state permitting and inspection requirements, there is a need for more frequent inspections to ensure its continued safety and effectiveness in flood control. Additionally, the dam's emergency action plan and risk management measures need to be updated to meet modern guidelines for dam safety.
As part of the flood risk reduction infrastructure in Seminole County, Oklahoma, SCS-Big Wewoka Creek Site-23 plays a crucial role in protecting the surrounding area from potential inundation. With a focus on maintaining and improving the dam's functionality, it is essential for the state regulatory agency, OWRB, to implement regular inspections and risk assessment measures to mitigate any potential hazards associated with the dam. Water resource and climate enthusiasts should closely monitor the management and maintenance of this important earth dam to ensure the safety and resilience of the community it serves.
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-Big Wewoka Creek Site-23
Where does the data for Scs-Big Wewoka Creek Site-23 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.
