Summary
Built in 1989 by USDA NRCS, this earth dam stands at 20.2 feet high and has a storage capacity of 139 acre-feet. With a controlled spillway and a low hazard potential, this dam serves a vital role in providing water for irrigation purposes in the region.
Managed by the OWRB and falling under state jurisdiction, Oknoname 30202 undergoes regular inspections and enforcement to ensure its structural integrity. Despite being classified as "Very High Risk," with a risk score of 1, the dam's condition remains "Not Rated." With only one valve outlet gate and a drainage area of 0.32 square miles, this dam plays a crucial role in managing water resources in the area while maintaining a low risk level for potential hazards.
With its location in a rural area without associated structures, Oknoname 30202 remains a key piece of infrastructure for water management. While it may lack updated inspection data since 2010, the dam's importance in providing irrigation water to the region cannot be understated. As a significant contributor to water resource management in Oklahoma, this dam showcases the intersection of private ownership, state regulation, and environmental stewardship in sustaining water availability for agricultural needs 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.
