Summary
With a height of 22 feet and a storage capacity of 118 acre-feet, this earth dam serves the primary purpose of providing water for agricultural irrigation in the area. Despite being privately owned and not regulated by the state, the dam has a low hazard potential and has not been rated for its current condition.
Even though Gallaway Lake Dam does not have a spillway or outlet gates, it plays a crucial role in storing water for irrigation purposes in the region. The dam covers a surface area of 10 acres and is situated within a drainage area of 87 square miles. Despite its age, the dam has not undergone any modifications or inspections in recent years, highlighting the need for continued monitoring and maintenance to ensure its safety and functionality for the surrounding community.
Although Gallaway Lake Dam is privately owned and not under state jurisdiction, its importance in providing water for irrigation cannot be understated. With its low hazard potential and unregulated status, it serves as a vital resource for local farmers and highlights the need for ongoing monitoring and maintenance to ensure its continued operation and safety for the community.

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.
