Scs-Cherokee Sandy Site-15 dam
Scs-Cherokee Sandy Site-15
Located in Garvin County, Oklahoma, the SCS-Cherokee Sandy Site-15 dam is a critical infrastructure designed by the USDA NRCS to manage flood risk along the TR-Cherokee Sandy Creek. Completed in 1962, this earth dam stands at a height of 30 feet with a hydraulic height of 27 feet, providing a storage capacity of 137 acre-feet for floodwaters. With a controlled spillway and low hazard potential, the dam serves as a vital resource for flood risk reduction in the region.
Managed by the Oklahoma Water Resources Board and regulated by the state, SCS-Cherokee Sandy Site-15 is inspected every five years to ensure its structural integrity and effectiveness in flood control. Despite its age, the dam has not been rated for its condition, indicating the need for further assessment. The presence of a single valve outlet gate and the absence of associated structures highlight the simplicity of the design, emphasizing functionality and practicality in managing water resources in the area.
In the event of emergencies, such as high discharge or potential breaches, the dam is equipped to handle such situations with emergency action plans and risk management measures in place. With a very high risk assessment rating, stakeholders and officials are continuously working towards improving the dam's resilience and capacity to withstand extreme weather events, making it a key asset for water resource and climate enthusiasts invested in sustainable infrastructure development.

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-Cherokee Sandy Site-15
Where does the data for Scs-Cherokee Sandy Site-15 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.
