Scs-Big Wewoka Creek Site-25 dam
Scs-Big Wewoka Creek Site-25
SCS-Big Wewoka Creek Site-25, also known as Del-Mar Lake, is a state-regulated water resource located in Seminole County, Oklahoma. Constructed in 1959 by the USDA NRCS, this earth dam stands at a height of 30 feet and has a storage capacity of 315 acre-feet, serving primarily for flood risk reduction along TR-Coon Creek. With a controlled spillway and a low hazard potential, this site has a very high risk assessment rating, indicating the need for diligent risk management measures.
Managed by the Oklahoma Water Resources Board, SCS-Big Wewoka Creek Site-25 has not been rated for its current condition but undergoes inspections every 5 years, with the last inspection dated back to 1980. Despite its age, the dam's purpose remains critical in safeguarding the surrounding area from potential flooding events, with a maximum discharge capacity of 1100 cubic feet per second. With a single valve outlet gate and a surface area of 22 acres, this water resource stands as a testament to effective flood risk mitigation efforts in the region.
As a key infrastructure project in flood risk reduction, SCS-Big Wewoka Creek Site-25 plays a vital role in protecting the community of Wewoka and its surroundings. With the potential for high-risk situations, it is crucial that the emergency action plan and risk management measures are regularly updated and maintained to ensure the safety and well-being of the area's residents. This site serves as a reminder of the importance of proactive water resource management in the face of changing climate patterns and increasing flood risks.

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-25
Where does the data for Scs-Big Wewoka Creek Site-25 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.
