Summary
This earth dam, completed in 1999, stands at a height of 19.7 feet and has a length of 250 feet, with a storage capacity of 57 acre-feet. Despite its low hazard potential and moderate risk assessment, the dam is regulated and inspected by the Mississippi Department of Environmental Quality to ensure its safety and compliance with state guidelines.
With a normal storage capacity of 33 acre-feet and a surface area of 4.9 acres, B Harvey Number 1 Dam provides a valuable resource for water-based activities and wildlife habitat in the Wilkinson County area. Although the dam's condition assessment is currently not rated, its design as an earth dam with a buttress core reflects a sturdy construction that has stood the test of time. The dam's uncontrolled spillway and minimal associated structures contribute to its simplicity and effectiveness in managing water flow along the Buffalo River.
Enthusiasts of water resources and climate will appreciate the significance of B Harvey Number 1 Dam in providing recreational opportunities and maintaining ecological balance in the region. As a privately-owned facility with state regulation and oversight, the dam serves as a model for sustainable water management practices and the importance of maintaining infrastructure for both human and environmental benefit. With its strategic location and moderate risk assessment, B Harvey Number 1 Dam stands as a testament to effective water resource management in Mississippi.

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.
