Summary
Completed in 1965, this earth-type dam stands at a height of 19 feet and has a length of 660 feet, with a storage capacity of 60 acre-feet. The dam serves multiple purposes and is primarily used for flood control on the TR-Campbell Creek.
Despite being classified as low hazard potential, Oknoname 073003 is considered to have a very high risk level, with a risk assessment rating of 1. The dam features a controlled spillway and a single valve outlet gate. While the dam has not been rated for its condition, it undergoes inspections every 5 years, with the last inspection conducted in January 2010. The dam is not operated by the US Army Corps of Engineers and does not have an Emergency Action Plan in place.
Water resource and climate enthusiasts will find Oknoname 073003 an interesting case study due to its unique design features and risk assessment. The dam's location in Kingfisher County on the TR-Campbell Creek adds to its significance in terms of local water resource management. As a privately owned structure with state regulation, the dam showcases the importance of public-private partnerships in ensuring the safety and sustainability of 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.
