Scs-Sandy Creek Site-20 dam
Scs-Sandy Creek Site-20
SCS-Sandy Creek Site-20 in Pontotoc County, Oklahoma, is a state-owned earth dam built in 1965 by the USDA NRCS for flood risk reduction along Coon Creek. The dam stands at a height of 31 feet with a length of 1550 feet, providing a storage capacity of 825 acre-feet and a maximum discharge of 6380 cubic feet per second. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure its structural integrity.
Despite being rated as having a low hazard potential, the site has a very high risk assessment due to its critical role in flood risk reduction for the surrounding area. The dam has a controlled spillway and is equipped with a single valve outlet gate for water release. While the condition assessment is currently not rated, the dam is regularly inspected every five years to maintain its functionality and safety measures. The location in Ada, Oklahoma, under the jurisdiction of the OWRB, highlights the importance of this structure in managing water resources and climate-related risks in the region.
Overall, SCS-Sandy Creek Site-20 serves as a vital infrastructure for water resource management and flood control in Pontotoc County. With its strategic design and state oversight, the dam plays a crucial role in mitigating potential flood risks along Coon Creek, safeguarding the surrounding communities from water-related disasters. As a key component of the local water management system, the site underscores the importance of proactive measures in addressing climate challenges and ensuring the resilience of water resources for the future.

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-20
Where does the data for Scs-Sandy Creek Site-20 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.
