Summary
This dam on the TR-CANADIAN RIVER stands at a height of 24 feet and a length of 3400 feet, with a storage capacity of 60 acre-feet. Despite being categorized as low hazard potential, it is state-regulated and undergoes regular inspections, with a controlled spillway and a valve outlet gate for water management.
Managed by the Natural Resources Conservation Service, Oknoname 063028 plays a crucial role in water resource management in Hughes County, Oklahoma. Its primary purpose is designated as "Other," with a very high risk assessment rating of 1. While the dam's condition is not currently rated, it meets state regulatory standards for inspection, enforcement, and permitting. With a history of state jurisdiction and regulatory oversight by the OWRB, this dam serves as a vital infrastructure for maintaining water resources in the region.
The dam's construction and design reflect a commitment to sustainable water management practices, with a stone core and soil foundation ensuring structural integrity. The presence of a single valve outlet gate allows for controlled release of water, while the dam's maximum discharge capacity of 450 cubic feet per second ensures flood protection for the surrounding area. As a key component of the Tulsa District's water infrastructure, Oknoname 063028 stands as a testament to the importance of effective dam management in mitigating climate-related risks and safeguarding 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.
