Summary
The dam, situated on TR-MISSION CR, is regulated by the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement.
Despite being classified as having a low hazard potential, Oknoname 113021 is considered to have a very high risk level, with a risk assessment ranking of 1. The dam features a controlled spillway and an outlet gate with a valve. While the condition assessment is marked as "Not Rated," the last inspection was conducted in August 2006 with an inspection frequency of every 5 years. Although no emergency action plan (EAP) has been prepared or updated for this dam, it is important to note that proper risk management measures should be implemented to mitigate potential risks associated with its high-risk classification.
For water resource and climate enthusiasts, Oknoname 113021 serves as a noteworthy structure in Bartlesville, Oklahoma, showcasing the intricate balance between water management and environmental stewardship. With its unique design and high-risk classification, this earth dam stands as a testament to the importance of regular monitoring, maintenance, and risk assessment in safeguarding our water resources for future generations.

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.
