Summary
Built in 1970, this earth dam stands at a height of 32 feet and has a storage capacity of 80 acre-feet. With a low hazard potential and a very high risk assessment rating of 1, this dam is regulated and inspected by the Oklahoma Water Resources Board (OWRB) to ensure its safety and compliance with state regulations.
The dam features a controlled spillway, with a width of 1 foot and a maximum discharge capacity of 800 cubic feet per second. It is equipped with a single valve outlet gate for water release. Although the condition of the dam is not rated, it undergoes inspections every 5 years to assess its structural integrity and safety. Despite its low hazard potential, the risk assessment for Oknoname 051034 is considered very high, emphasizing the importance of proper maintenance and monitoring to prevent any potential risks or failures.
As an essential structure for water resource management, Oknoname 051034 plays a crucial role in regulating water flow and storage in the area. With its strategic location and design features, this dam serves its primary purpose effectively while being subject to regular inspections and regulatory oversight to ensure public safety and environmental protection.

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.
