Summary
Built in 1969 by the Natural Resources Conservation Service, this earth dam stands at a height of 32.3 feet with a length of 370 feet, providing a storage capacity of 255 acre-feet for recreational purposes. The dam is designed with a buttress core and an uncontrolled spillway, making it a low hazard potential structure.
With a drainage area of 110 acres and a surface area of 9 acres, Garby Lake Dam serves as a vital water resource in the region, offering a normal storage capacity of 99 acre-feet. Although not currently regulated by the state, the dam undergoes regular inspections every 5 years to ensure its safety and functionality. Despite being labeled as having a moderate risk assessment, the dam's condition is currently not rated, indicating the need for further evaluation and potential risk management measures.
Overall, Garby Lake Dam plays a crucial role in providing recreational opportunities while also serving as a water management infrastructure in the area. Its historical significance and ongoing maintenance efforts highlight the importance of sustainable water resource management for the community and the environment.

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.
