Summary
Owned privately, this earth dam with a buttress core stands at a height of 16 feet and has a storage capacity of 150 acre-feet. The dam is regulated by the Mississippi Department of Environmental Quality and is inspected, permitted, and enforced by state agencies to ensure its safety and compliance with regulations.
Managed by the USDA NRCS, the dam's spillway is uncontrolled, and it has an undetermined hazard potential with a moderate risk assessment score. Despite not being rated for its condition, the dam remains in operation and serves as a vital resource for water storage and recreational activities. While there are no associated structures or locks with the dam, its location along the Hobolochitto Creek W tributary makes it a crucial component of the local water resource infrastructure.
Water resource and climate enthusiasts will find W H Amacker Lake Dam to be a fascinating example of a privately-owned earth dam designed for both water storage and recreational purposes in Mississippi. With its regulatory oversight and risk management measures in place, the dam plays a significant role in balancing the needs of water conservation and public enjoyment. Its presence along the tributary underscores the importance of sustainable water management practices in the region, making it a noteworthy site for those interested in the intersection of water resources and environmental conservation.

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.
