Summary
Built in 1958, this dam stands at 18 feet tall with a length of 350 feet, providing a storage capacity of 75 acre-feet. The primary purpose of this structure is classified as 'Other', with a low hazard potential and a very high risk assessment rating.
Managed by the Oklahoma Water Resources Board, Oknoname 049005 is regulated, inspected, and enforced by state authorities. The dam, situated on TR-Washington Creek, features a controlled spillway with a width of 1 foot and a single valve outlet gate. Despite not having a condition rating, the dam is deemed to meet safety guidelines, although an emergency action plan (EAP) has not been prepared.
Given its significant risk assessment and high storage potential, water resource and climate enthusiasts should pay attention to Oknoname 049005 for any potential implications on water management and emergency response strategies in the surrounding Garvin County area. Regular inspections and risk management measures are crucial for ensuring the safety and integrity of this essential infrastructure.

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.
