Last Updated: February 24, 2026
Oknoname 30168 is a privately owned earth dam located in Seminole, Oklahoma, along the North Canadian River.
Summary
Constructed in 1994 by USDA NRCS, this dam serves the primary purpose of flood risk reduction, with a height of 17.5 feet and a storage capacity of 95 acre-feet. The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections and enforcement to ensure its safety and efficacy in managing floodwaters.
With a low hazard potential and a very high risk assessment rating, Oknoname 30168 is a crucial infrastructure for mitigating flood risks in the area. It features a controlled spillway and a valve outlet gate for efficient water management. Although the dam's condition is currently not rated, it meets state regulatory standards and has a history of effective flood control. Despite being privately owned, the dam plays a significant role in protecting nearby communities from the impacts of flooding and ensuring water resource sustainability in the region.
As a key component of flood risk reduction along the North Canadian River, Oknoname 30168 plays a vital role in the overall water management strategy in Seminole, Oklahoma. With its strategic location and design by USDA NRCS, the dam serves as a critical infrastructure for safeguarding lives and properties against flooding events. The collaboration between private ownership and state regulatory agencies like OWRB demonstrates a proactive approach towards climate resilience and water resource management in the region.

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.
