Summary
This private earth dam, with a height of 28 feet, holds a storage capacity of 495 acre-feet on the TR-Topasaw Creek. Despite its low hazard potential and moderate risk assessment, the dam is state-regulated by the Mississippi Department of Environmental Quality, with permitting, inspection, and enforcement in place to ensure its safety and compliance with regulations.
The dam, with a buttress core and soil foundation, features an uncontrolled spillway and outlet gates. While it has not been rated for its condition assessment, the dam is currently not considered to be at risk. The surrounding area, including Webster County, benefits from the recreational opportunities provided by the reservoir created by the dam. With its picturesque location and potential for outdoor activities, Pat Gibson Lake Dam serves as a valuable water resource for the community while being closely monitored to mitigate any potential risks.
As water resource and climate enthusiasts, it is important to understand the role that dams like Pat Gibson Lake Dam play in providing recreational opportunities and water storage in Mississippi. By recognizing the regulatory oversight and risk management measures in place, we can appreciate the careful balance between utilizing water resources for human benefit while ensuring the safety and integrity of these vital structures for the environment and surrounding communities.

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.
