Summary
Built in 1945, this Earth-type dam stands at a height of 26 feet and stretches 308 feet in length. With a storage capacity of 83 acre-feet, it serves a primary purpose classified as "Other." The dam's hazard potential is rated as low, but the risk assessment indicates a very high risk level.
The dam is regulated by the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections, with the last inspection conducted in July 2005. Despite being in operation for over 75 years, the dam's condition assessment is listed as "Not Rated." It is equipped with a controlled spillway and a single valve outlet gate. The dam's location in Washington and its proximity to the city add to its significance in the region.
Overall, Oknoname 087004 plays a crucial role in water resource management in the area, ensuring flood control and water supply. Its historical significance and ongoing operational oversight by state regulators make it an essential infrastructure for climate and water enthusiasts to monitor and study in the context of changing environmental conditions and water resource management practices.

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.
