Summary
Completed in 1930, this dam stands at 18 feet tall and has a storage capacity of 895 acre-feet, with a normal storage level of 695 acre-feet. The dam has a surface area of 92 acres and a maximum discharge rate of 6,200 cubic feet per second. The spillway is controlled with a width of 2 feet, and there is one valve for outlet gates.
Despite its low hazard potential, Dow is classified as having a very high risk, with a rating of 1. The dam is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state regulation, permitting, inspection, and enforcement. The last inspection was conducted in May 2011, with a scheduled frequency of every 5 years. The condition assessment of the dam is currently not rated, and there is no Emergency Action Plan (EAP) prepared.
With its rich history dating back to the early 20th century, Dow serves as an important recreational resource in the area. As climate change continues to impact water resources, the management and maintenance of structures like Dow become crucial in ensuring the safety and sustainability of our water supply.

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.
