Summary
Built in 1970, this earth-type dam stands 22 feet high and spans 250 feet in length, with a storage capacity of 60 acre-feet. Despite its low hazard potential, the dam's risk assessment is rated as very high, indicating the importance of ongoing monitoring and maintenance.
Managed by the Oklahoma Water Resources Board, Oknoname 047001 is equipped with a controlled spillway and a single valve outlet gate for water release. While the dam has not been inspected since December 2010, it is regulated, permitted, inspected, and enforced by the state, ensuring its structural integrity and public safety. The risk of failure for this dam is deemed very low, but it is crucial to adhere to proper risk management measures to mitigate any potential hazards.
For water resource and climate enthusiasts, Oknoname 047001 serves as a notable example of effective flood risk reduction infrastructure in Oklahoma. With a focus on safety and regulatory compliance, this dam plays a vital role in protecting the surrounding community from potential flooding events. As climate patterns continue to shift, maintaining and assessing the condition of structures like Oknoname 047001 will be essential in ensuring the resilience of water resources in the face of evolving environmental challenges.

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.
