Summary
Built in 1971 by the USDA NRCS, this Earth-type dam stands at a height of 19 feet and has a storage capacity of 89 acre-feet. With a surface area of 3 acres and a maximum discharge of 185 cubic feet per second, Garner Lake is regulated by the Oklahoma Water Resources Board and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite its low hazard potential, Garner Lake is considered to have a very high risk due to its location and potential impact in the event of a breach. Emergency action plans have not been rated or updated recently, highlighting the importance of ongoing risk assessment and management measures for this reservoir. The controlled spillway and outlet gates help regulate water levels, while the surrounding stone core and soil foundation provide structural support to the dam, ensuring its stability and integrity over time.
The presence of Garner Lake serves as a vital resource for irrigation in the region, supporting agricultural activities and water supply for nearby communities. As a part of the Fort Worth District, the reservoir plays a crucial role in water management and conservation efforts in Oklahoma. With its strategic location and design, Garner Lake demonstrates the importance of sustainable water resource management in the face of changing climate conditions and increasing water demands.

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.
