Scs-Cobb Creek Site-004 dam
Scs-Cobb Creek Site-004
SCS-Cobb Creek Site-004, located in Caddo, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS in 1957 for flood risk reduction along Fivemile Creek. This impressive structure has a dam height of 54 feet and a hydraulic height of 49 feet, with a storage capacity of 1033 acre-feet and a surface area of 32 acres. Despite being categorized as having a low hazard potential, the risk assessment for this dam site is rated as very high due to its age and condition assessment not being rated.
Managed by the OWRB and situated in the Tulsa District, the SCS-Cobb Creek Site-004 dam plays a crucial role in mitigating potential flooding in the region. Its controlled spillway, valve outlet gates, and stone core foundation contribute to its structural integrity and operational efficiency. While the last inspection date dates back to 1980, the dam is inspected every five years, although its emergency action plan status, risk management measures, and inundation maps preparation are not currently updated or in compliance with guidelines.
For water resource and climate enthusiasts, SCS-Cobb Creek Site-004 serves as a fascinating case study in dam infrastructure and risk assessment. The presence of a very high risk rating despite a low hazard potential underscores the importance of regular inspections, maintenance, and emergency preparedness for aging structures like this. As the dam continues to play a vital role in flood risk reduction along Fivemile Creek, ongoing efforts to improve its condition assessment, emergency action plan, and risk management measures will be crucial in ensuring the safety and resilience of the surrounding communities and ecosystems.

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-Cobb Creek Site-004
Where does the data for Scs-Cobb Creek Site-004 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.
