Scs-Sandy Creek Site-11 dam
Scs-Sandy Creek Site-11
SCS-Sandy Creek Site-11, located in Pontotoc, Oklahoma, is a state-regulated earth dam designed by the USDA NRCS in 1976 for flood risk reduction along the Canadian Sandy Creek. The dam stands at a height of 38 feet and spans 1550 feet, with a storage capacity of 1328 acre-feet and a surface area of 30 acres. Despite being rated as having a low hazard potential, the risk assessment for this dam is very high, highlighting the need for proper maintenance and management.
The dam features a controlled spillway and a single valve outlet gate for water release. Although the condition assessment is currently marked as "Not Rated," regular inspections are conducted every 5 years, with the last inspection dating back to January 1980. The dam is under the jurisdiction of the state regulatory agency OWRB and falls under the supervision of the Natural Resources Conservation Service. With a risk management plan in place, this site serves as a vital infrastructure for flood control in the region, safeguarding the surrounding area from potential inundation.
In the event of an emergency, the dam's emergency action plan status is unknown, emphasizing the need for updated protocols and guidelines. Despite its age, SCS-Sandy Creek Site-11 continues to play a crucial role in mitigating flood risks in the area, thanks to its strategic location and design. As water resource and climate enthusiasts, it is essential to recognize the significance of such structures in ensuring the safety and sustainability of our communities amidst changing environmental conditions.

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-Sandy Creek Site-11
Where does the data for Scs-Sandy Creek Site-11 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.
