Summary
Completed in 1985, the dam stands at 27 feet high and has a storage capacity of 35 acre-feet. The primary purposes of the dam include fire protection, stock, small fish pond, and other uses, making it a valuable resource for the local community.
Despite being privately owned, Gibson Lake Dam has significant hazard potential and is classified as a significant risk. However, the condition of the dam has not been rated, and there is no recent data on inspections or emergency preparedness. The dam's risk management measures and guidelines for emergency action plans are also unclear, highlighting the importance of further assessment and maintenance to ensure its safety and functionality.
Given its critical role in providing water storage and protection for the surrounding area, water resource and climate enthusiasts may find Gibson Lake Dam to be an intriguing subject for further study and monitoring. With its unique design and purpose, this dam serves as a key component in the local ecosystem and warrants attention to ensure its continued effectiveness in water management and conservation efforts.

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.
