Summary
Completed in 1996, this earth dam stands at 17 feet high with a hydraulic height of 16 feet and a length of 703 feet. With a storage capacity of 113 acre-feet, this dam helps control water flow in the area while covering a drainage area of 140.8 square miles.
Despite its low hazard potential and moderate risk assessment, Garner Dam is not currently rated for its condition assessment. The spillway type is uncontrolled with a width of 10 feet, ensuring proper water discharge during high flow events. While the dam has not been modified in recent years, it plays a crucial role in managing water resources and mitigating flood risks in the region.
Owned privately, Garner Dam does not fall under state jurisdiction or regulation. Its construction was funded and overseen by private entities, highlighting the importance of collaboration in water resource management. With its strategic location and design features, Garner Dam stands as a vital infrastructure for maintaining water quality and safeguarding against potential climate impacts in the area.

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.
