Scs-Delaware Creek Site-003 dam
Scs-Delaware Creek Site-003
SCS-Delaware Creek Site-003 is a state-owned dam located in Wapanucka, Johnston County, Oklahoma, along TR-Sandy Creek. Constructed in 1971 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a length of 1990 feet, providing flood risk reduction for the area. With a maximum storage capacity of 589 acre-feet and a normal storage of 107 acre-feet, the dam serves as a crucial infrastructure for managing water resources in the region.
Managed by the Oklahoma Water Resources Board, SCS-Delaware Creek Site-003 has a significant hazard potential with a very high risk assessment rating. Despite being in operation for several decades, the dam's condition assessment is currently not rated, and the last inspection was conducted in December 2005. The dam features a controlled spillway, outlet gates, and is state-regulated with permitting, inspection, and enforcement conducted by OWRB. In case of emergencies, there is no Emergency Action Plan prepared as of the latest data update in May 2021.
As a key structure for flood risk reduction in Johnston County, SCS-Delaware Creek Site-003 plays a vital role in managing water resources and protecting the local community from potential hazards. With its stone core and soil foundation, the dam is designed to withstand hydraulic pressures and maintain its structural integrity. While the dam's risk assessment indicates a very high level of potential danger, ongoing monitoring and enforcement by state regulatory agencies are essential to ensure the safety and stability of the dam for years to come.
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-Delaware Creek Site-003
Where does the data for Scs-Delaware Creek Site-003 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 Significant 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.
