Summary
This dam stands at a height of 29 feet with a hydraulic height of 32 feet and a structural height of 35 feet, serving the purpose of water resource management along the CIMARRON river. With a storage capacity of 128 acre-feet and a surface area of 10.5 acres, this dam plays a vital role in regulating the flow of water in the region.
Despite being classified as a low hazard potential structure, Oknoname 30172 is under the regulatory jurisdiction of OWRB, with state permitting, inspection, and enforcement in place. The dam features a controlled spillway with a width of 1 foot and includes a valve outlet gate for water release. The risk assessment for this dam is rated as 'Very High (1)', emphasizing the importance of proper management and maintenance to ensure the safety and functionality of the structure.
In the event of an emergency, Oknoname 30172 does not have an Emergency Action Plan (EAP) prepared, highlighting the need for proactive measures to address potential risks. With a drainage area of 422 square miles, this dam plays a crucial role in water resource management in the region, and its condition assessment remains unrated as of the last inspection in 2010. Climate and water resource enthusiasts will find Oknoname 30172 a fascinating example of the intersection between infrastructure, regulation, and environmental stewardship in managing water resources.

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.
