Summary
Standing at a height of 12 feet, the dam has a storage capacity of 70 acre-feet and is regulated by the Mississippi Department of Environmental Quality. Despite its low hazard potential, the dam's risk assessment is moderate, highlighting the importance of ongoing monitoring and maintenance.
The dam features an uncontrolled spillway and is not currently rated for its condition. While it has not been modified in recent years, the dam is subject to regular state inspections and enforcement measures to ensure its safety. With a risk management plan in place and a designated emergency action plan, Williams Lake Dam serves as both a recreational asset and a critical component of the local water resource infrastructure.
As water resource and climate enthusiasts continue to monitor the impact of climate change on dams and reservoirs, Williams Lake Dam stands as a reminder of the importance of maintaining and enhancing these vital structures to ensure the safety and sustainability of our water resources. With proper oversight and maintenance, dams like Williams Lake Dam can continue to provide valuable recreational opportunities while protecting communities from potential hazards associated with flooding and water management.

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.
