Summary
Completed in 1970, this structure stands at a height of 20 feet and boasts a storage capacity of 66 acre-feet. The dam spans 476 feet in length and sits on the TR Little Beaver Creek, regulated by the Oklahoma Water Resources Board. Despite being categorized as low-hazard, the risk assessment for Oknoname 137063 indicates a very high level of risk, making it crucial for proper management and monitoring.
With a controlled spillway and a single valve outlet gate, Oknoname 137063 is designed to handle a maximum discharge of 4100 cubic feet per second. Although the dam's condition remains unrated, it undergoes inspections every 5 years, with the last one conducted in September 2011. The presence of emergency action plans, inundation maps, and risk management measures for this dam is unclear, highlighting the need for further assessment and preparedness in case of unforeseen events. As an enthusiast of water resources and climate, the unique characteristics and risk profile of Oknoname 137063 present an intriguing case study in dam safety and management.

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.
