Summary
The dam, built on the QUARTER MASTER/ WASHITA RIVER, serves as a critical structure for water resource management in the area.
Although the dam has a low hazard potential, it is rated as having a very high risk due to its condition assessment being labeled as "Not Rated." Despite being state-regulated and inspected, with necessary permits and enforcement in place, the last inspection date dates back to 2010, raising concerns about the current state of the dam's maintenance. With a controlled spillway and one outlet gate, Oknoname 30217 presents a vital piece of infrastructure that requires updated assessments and risk management measures to ensure its continued functionality and safety for the surrounding community and environment.
Water resource and climate enthusiasts monitoring Oknoname 30217 should advocate for regular inspections and a condition assessment to be conducted promptly. With a risk assessment classifying it as very high, the dam's maintenance and emergency preparedness should be a top priority for the relevant authorities. By addressing the potential risks and implementing necessary measures, this dam can continue to support water management efforts in the region effectively while safeguarding against any potential hazards.

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.
