Summary
The dam stands at a height of 27 feet and has a storage capacity of 130 acre-feet, with a normal storage level of 63 acre-feet. With a surface area of 5 acres, the dam serves a primary purpose classified as "Other," indicating its versatility in water resource management.
Despite its low hazard potential, Oknoname 123008 is subject to state regulation, inspection, and enforcement by the Oklahoma Water Resources Board. The dam features a controlled spillway and a single valve outlet gate for water release. In the event of an emergency, the dam's Emergency Action Plan status is not rated, highlighting the need for further assessment and preparation to meet guidelines for risk management.
With a maximum discharge capacity of 960 cfs, Oknoname 123008 presents a very high risk profile, marked by a DSAC-assigned risk level of 1. As climate change continues to impact water resources, understanding the condition and management of dams like Oknoname 123008 is crucial for ensuring the safety and sustainability of water infrastructure in Oklahoma.

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.
