Summary
The earth dam stands at a height of 28 feet and has a storage capacity of 60 acre-feet. With a maximum discharge capacity of 0, the dam serves multiple purposes including fire protection, stock or small fish pond, and recreation across its 4-acre surface area.
Managed by a private owner, Gibson Dam is not regulated by the state and has a high hazard potential. Despite its condition being unrated, the dam continues to play a crucial role in managing the flow of the TR Spencer Creek. Enthusiasts of water resources and climate will find the dam's design intriguing, with a buttress core type and unlisted/unknown foundation construction.
While Gibson Dam currently does not have an Emergency Action Plan (EAP) in place, its location in Ralls County, Missouri, has been a key point for potential risk assessments and management measures. As a non-USACE dam, its impact on the local environment and surrounding communities underscores the importance of regular inspections and maintenance to ensure its continued functionality and safety. For those interested in the intersection of infrastructure, water resource management, and climate adaptation, Gibson Dam provides a fascinating case study in private dam ownership and multi-purpose functionality.

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.
