Summary
With a dam height of 49 feet and a hydraulic height of 42 feet, the lake offers a storage capacity of 1,563 acre-feet and covers a surface area of 91 acres. Completed in 2017, the lake has a controlled spillway with a width of 36 feet, ensuring safe water release during periods of high discharge.
Managed by Barker & Associates Inc., Tim Halter Lake is regulated by the Oklahoma Water Resources Board, with state permitting, inspection, and enforcement in place to ensure compliance with safety standards. Despite a low hazard potential, the lake is rated as having a very high risk due to its location, emphasizing the importance of effective risk management measures. With a congressional representative from the area being Markwayne Mullin (R), the lake serves as a valuable resource for climate enthusiasts and water resource management stakeholders.
Overall, Tim Halter Lake provides a picturesque setting for outdoor enthusiasts to enjoy recreational activities while also serving as a vital water resource in the region. Its completion in 2017 reflects a commitment to sustainable water management practices, with a focus on safety and risk assessment to ensure the continued enjoyment and preservation of this important water source.

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.
