Scs-Pennington Creek Site-2 dam
Scs-Pennington Creek Site-2
SCS-Pennington Creek Site-2, located in Johnston County, Oklahoma, is a state-regulated earth dam constructed in 1953 by the USDA NRCS. The primary purpose of this dam is flood risk reduction along the TR-Pennington Creek. Standing at a height of 30 feet with a hydraulic height of 25 feet, this dam spans a length of 1,010 feet and has a maximum discharge capacity of 3,200 cubic feet per second.
With a normal storage capacity of 207 acre-feet and a maximum storage of 1,010 acre-feet, SCS-Pennington Creek Site-2 covers a surface area of 38 acres. The dam is equipped with a controlled spillway and a single valve outlet gate. Despite being rated as having a low hazard potential, the dam's risk assessment is classified as very high (1). The last inspection of the structure was conducted in 1980, with an inspection frequency of every 5 years.
As an essential infrastructure for managing flood risks in the region, the SCS-Pennington Creek Site-2 serves as a critical component of water resource management in the area. Its design and construction by the USDA NRCS reflect a commitment to safeguarding the local community from potential flooding events. Moving forward, continued monitoring and maintenance of this dam will be crucial to ensure its effectiveness in reducing flood risks and protecting the surrounding environment.

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-Pennington Creek Site-2
Where does the data for Scs-Pennington Creek Site-2 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.
