Summary
Completed in 1977, this dam stands at 26 feet tall and has a storage capacity of 150 acre-feet. With a controlled spillway and a maximum discharge of 1420 cubic feet per second, Kelly Tom serves as a critical infrastructure for flood control in the area.
Managed by the Oklahoma Water Resources Board, Kelly Tom is subject to state regulations, inspections, and enforcement to ensure its proper functioning. Despite its low hazard potential, the dam is categorized as having a very high risk due to its location and purpose. With a valve outlet gate and a designated emergency action plan, Kelly Tom is equipped to handle potential emergencies and protect downstream communities in case of a breach.
For water resource and climate enthusiasts, Kelly Tom serves as a prime example of the vital role dams play in mitigating flood risks and managing water resources. Its design, construction, and ongoing maintenance highlight the complex interplay between infrastructure development, regulatory oversight, and emergency preparedness in safeguarding communities against natural disasters.

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.
