Summary
Completed in 1976, this dam stands at a height of 30 feet and has a capacity of 306 acre-feet. It sits on the KEEL SANDY CR river and is under the jurisdiction of the OWRB, with a low hazard potential and a very high risk assessment rating.
This dam features a controlled spillway and one outlet valve, with a structural height of 30 feet and a hydraulic height of 28 feet. Although it has not been inspected since 1980, it is still deemed to be in a not rated condition. The surrounding area covers 8 acres and has a normal storage capacity of 32 acre-feet, with a maximum discharge of 360 cubic feet per second. Owned by the state of Oklahoma, this dam plays a crucial role in managing water resources and protecting against potential flooding events in the region.
Overall, SCS-Cherokee Sandy Site-06 serves as a vital water management structure in Garvin, Oklahoma, contributing to flood risk reduction efforts and ensuring the safety of nearby residents. With its low hazard potential and high risk assessment rating, this earth dam represents a key component of the state's water infrastructure. As climate change continues to impact weather patterns, the importance of well-maintained dams like this one becomes increasingly apparent for ensuring the resilience of communities in the face of environmental challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
