Summary
It was designed by the USDA NRCS and completed in 2004 with a primary purpose of serving as a Fish and Wildlife Pond. The dam has a height of 19.6 feet and a storage capacity of 70.78 acre-feet, with a surface area of 7.55 acres and a drainage area of 128 square miles.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular inspections, with the last inspection conducted in September 2011. Despite being classified as having a low hazard potential, the dam's risk assessment is rated as very high (1). It has a controlled spillway and one outlet gate, with a maximum discharge rate of 32.9 cubic feet per second. The dam is considered structurally sound, though its condition assessment is currently listed as "Not Rated".
Overall, Oknoname 30119 is a significant structure in the area, providing essential support for fish and wildlife habitats while also serving as a water resource for the surrounding community. Its design and construction reflect a commitment to environmental conservation and sustainable management of water resources in the region, making it a valuable asset for both wildlife enthusiasts and climate advocates alike.

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.
