Summary
Standing at a height of 16 feet and with a max storage capacity of 52 acre-feet, this dam on TR-YASHUA CR is regulated by the Oklahoma Water Resources Board and undergoes regular inspections and maintenance. Despite its low hazard potential, the risk assessment for this dam is rated as very high, emphasizing the importance of effective risk management measures.
Owned and maintained by a private entity, Oknoname 089009 serves as a recreational spot for the local community in Broken Bow. The dam's structure consists of stone core and soil foundation, with a controlled spillway measuring 1 foot in width. While the dam has not been rated for its condition assessment, it is equipped with a single valve outlet gate for water release. The risk assessment for this dam is marked as very high, necessitating strict adherence to safety protocols and emergency preparedness.
Although Oknoname 089009 has a relatively low hazard potential, its very high risk assessment underscores the need for proactive risk management strategies. With a history dating back to 1930, this earth dam continues to provide recreational opportunities while being subject to state regulations and inspections. As water resource and climate enthusiasts, it is crucial to monitor and address the potential risks associated with dams like Oknoname 089009 to ensure the safety and sustainability of our water infrastructure.

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.
