Summary
The dam, completed in 1940, spans 420 feet in length and stands at a height of 23 feet. It is classified as an Earth dam with a stone core and soil foundation, serving a primary purpose that falls under the category of "Other."
The dam's reservoir has a storage capacity of 120 acre-feet, with a maximum discharge of 250 cfs. It is regulated and inspected by the Oklahoma Water Resources Board, ensuring that it meets state permitting and enforcement requirements. Although the dam is considered to have a low hazard potential, it is categorized as having a very high risk due to its condition assessment not being rated.
For water resource and climate enthusiasts, Oknoname 111030 presents an interesting case study in dam management and risk assessment. With its location along the TR-COAL CREEK and its controlled spillway design, the dam plays a crucial role in water flow control in the area. The data available provides insight into the structural integrity of the dam and highlights the importance of regular inspections and risk management measures to ensure public safety and environmental protection in the face of potential emergencies.

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.
