Scs-Cherokee Sandy Site-08a dam
Scs-Cherokee Sandy Site-08a
SCS-Cherokee Sandy Site-08a, located in Garvin, Oklahoma, is a state-regulated dam designed by USDA NRCS with a primary purpose of flood risk reduction. This earth dam, completed in 1965, stands at a height of 27 feet and has a hydraulic height of 23 feet, with a length of 1350 feet. The dam has a storage capacity of 570 acre-feet and a normal storage of 55 acre-feet, serving the TR-WILLOW SANDY CREEK watershed.
With a significant hazard potential and a fair condition assessment, SCS-Cherokee Sandy Site-08a is in need of regular inspections and maintenance to ensure its continued effectiveness in flood risk reduction. The dam has a controlled spillway and one outlet valve, with a maximum discharge capacity of 1300 cfs. The risk assessment for this dam is rated as very high, highlighting the importance of proper risk management measures and emergency preparedness.
Overall, SCS-Cherokee Sandy Site-08a plays a crucial role in mitigating flood risks in the area and protecting the surrounding communities. With state regulation and oversight from OWRB, this dam requires ongoing attention to maintain its functionality and safeguard against potential hazards. For water resource and climate enthusiasts, this site serves as a reminder of the vital role that infrastructure plays in managing and adapting to 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-Cherokee Sandy Site-08a
Where does the data for Scs-Cherokee Sandy Site-08a 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 Significant 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.
