Summary
Built in 2001, this earth dam stands at 15.9 feet tall and spans 400 feet in length, creating a reservoir with a storage capacity of 58 acre-feet. Situated on the UNT of Standing Pine Creek, the dam has a low hazard potential and is not currently rated for its condition assessment.
Managed by the Mississippi Department of Environmental Quality, Joe Wall Dam is regulated, inspected, and enforced by the state agency to ensure its safety and compliance with environmental standards. With a moderate risk assessment score of 3, the dam poses a moderate level of risk and is closely monitored for any potential issues. Although there are no associated structures or locks, the dam features an uncontrolled spillway type and has a maximum discharge of 151 cubic feet per second.
Despite not being a federal-owned structure, Joe Wall Dam provides a valuable recreational resource for the local community, offering opportunities for fishing, boating, and other outdoor activities in a scenic setting. As a key part of the water resource infrastructure in the area, the dam plays a crucial role in managing the water flow of the Standing Pine Creek and contributing to the overall water management efforts 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.
