Summary
The dam, with a height of 22 feet and a storage capacity of 120 acre-feet, serves as a low hazard potential facility with a moderate risk assessment level. Despite not being rated for its current condition, the dam is subject to state regulation, inspection, and enforcement by the Mississippi Department of Environmental Quality.
Located within the Vicksburg District of the US Army Corps of Engineers, Galyon Lake Dam features an earth core type with buttress foundations and an uncontrolled spillway. While there are no associated structures or locks, the dam's primary purpose is to provide recreational opportunities for visitors. The surrounding area offers a serene setting for outdoor activities and wildlife observation, making it a popular destination for water resource and climate enthusiasts looking to explore the beauty of Mississippi's natural landscapes.
As a key part of the local water infrastructure, Galyon Lake Dam contributes to the conservation and management of water resources in the region. With its moderate risk assessment level and state-regulated status, the dam plays a crucial role in ensuring the safety and sustainability of the surrounding environment. For those interested in the intersection of water resources and climate impact mitigation, Galyon Lake Dam serves as a valuable case study in the efforts to balance recreational use with environmental stewardship.

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.
