Summary
This Earth buttress dam stands at a height of 20 feet and has a storage capacity of 122 acre-feet, making it suitable for low hazard potential activities. The dam is under the regulatory jurisdiction of the Mississippi Department of Environmental Quality, ensuring that it is inspected, enforced, and permitted in accordance with state regulations.
Located within the Vicksburg District, James Wennemark Dam offers a serene setting for water resource and climate enthusiasts to enjoy various recreational activities. While the dam's condition is currently not rated, its moderate risk assessment level indicates a need for ongoing risk management measures. With its uncontrolled spillway and limited associated structures, this dam serves as a valuable asset for the community, providing both leisure opportunities and essential water storage capabilities.
As an Earth buttress dam, James Wennemark Dam's design and construction reflect a balance of functionality and environmental considerations. While the dam's height and storage capacity may not be as extensive as larger structures, its role in supporting recreation and water management in the area is significant. With proper maintenance and oversight, this dam will continue to contribute to the local ecosystem and provide a valuable resource for residents and visitors alike.

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.
