Summary
Built in 1960, this dam stands at a height of 32 feet and has a maximum storage capacity of 380 acre-feet. The primary purpose of this dam is classified as "Other," with a low hazard potential and a very high risk assessment ranking.
Managed by the Oklahoma Water Resources Board, Flying Ranch No 1 is regulated, inspected, and enforced by state authorities to ensure its structural integrity and safety. The dam features a controlled spillway with a width of 2 feet and one valve outlet gate. Despite not having a condition assessment rating, the dam's risk management measures are under review due to its risk assessment classification as very high.
Situated along the TR-Little Buzzard Creek, Flying Ranch No 1 serves as a vital water resource for the surrounding area, providing storage for up to 220 acre-feet of water for various purposes. With its strategic location and state oversight, this dam plays a crucial role in managing water resources and mitigating potential risks in Le Flore County, Oklahoma.

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.
