Summary
This earth dam, with a height of 12 feet, provides a storage capacity of 56 acre-feet. The dam is regulated by the Mississippi Department of Environmental Quality and is inspected regularly to ensure its safety and compliance with state regulations.
Despite being classified as having an undetermined hazard potential and a moderate risk level, the condition of Jess Yancey Lake Dam is currently not rated. The dam features an uncontrolled spillway and does not have outlet gates or associated structures. While the risk level is considered moderate, the dam's emergency action plan status and risk management measures are unclear, leaving room for further assessment and improvement to mitigate potential risks.
Water resource and climate enthusiasts interested in Jess Yancey Lake Dam will find its location within the Vicksburg District and its association with the state of Mississippi's regulatory agencies intriguing. The dam's role in providing recreational opportunities in the area adds to its significance, making it a focal point for environmental monitoring and management efforts. With its unique design and operational features, Jess Yancey Lake Dam stands as a vital component of the local landscape, offering both challenges and opportunities for sustainable water resource management in the region.

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.
