Summary
Built in 1940, this dam stands at a height of 25 feet and has a length of 375 feet. It serves as a crucial structure along the TR-Cimarron River, with a primary purpose classified as "Other." The dam has a storage capacity of 51 acre-feet and a surface area of 4 acres, making it an essential resource for water management in the region.
Managed by the Oklahoma Water Resources Board, Oknoname 059046 is regulated, permitted, inspected, and enforced by the state agency. Despite its low hazard potential, the dam is considered to have a very high risk level due to its condition assessment being "Not Rated." With a controlled spillway and a single valve outlet gate, the dam is equipped to handle a maximum discharge of 2250 cubic feet per second. The risk management measures and emergency preparedness for this structure are currently not rated, indicating a potential area for improvement in ensuring the safety and reliability of Oknoname 059046.
Overall, Oknoname 059046 is an important water resource in Harper County, Oklahoma, with a rich history dating back to the 1940s. Its role in managing water flow along the TR-Cimarron River highlights the importance of maintaining and monitoring such structures to ensure the safety of surrounding communities and the environment. As water resource and climate enthusiasts, staying informed about the condition and risk assessment of dams like Oknoname 059046 is crucial in promoting sustainable water management practices and mitigating potential hazards.

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.
