Summary
Managed by the USDA NRCS, this earth dam stands at a height of 25.7 feet and serves primarily for recreation purposes, with a storage capacity of 96.4 acre-feet. The dam has a controlled spillway type with a width of 1 foot and a maximum discharge of 13.8 cubic feet per second. Despite its low hazard potential and not yet rated condition assessment, Oknoname 30228 is under state regulation by the Oklahoma Water Resources Board, ensuring regular inspection, permitting, and enforcement to maintain its safety and integrity.
Situated within the Fort Worth District of the US Army Corps of Engineers, Oknoname 30228 has not been modified since its construction and features a single outlet valve. The dam's risk assessment categorizes it as having a very high (1) risk level, prompting the need for effective risk management measures in the case of emergencies. Although the dam is privately owned, it falls under state jurisdiction, indicating that it is subject to Oklahoma's regulatory agencies for oversight. With its picturesque location and vital role in recreational activities, Oknoname 30228 stands as a testament to the intersection of water resource management and climate resilience 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.
