Summary
The dam is regulated by the Mississippi Department of Environmental Quality and serves as a flood risk reduction measure for the area. With a height of 23 feet and a capacity of 550 acre-feet, the dam plays a crucial role in managing water flow and protecting the surrounding community from potential flooding.
Constructed with an earth core and buttress design, Wendy Hill Upper Lake Dam has a low hazard potential and is currently rated as not assessed. Despite not having a specific completion year listed, the dam is regularly inspected by state authorities to ensure its structural integrity and effectiveness in flood risk mitigation. The dam features an uncontrolled spillway and a moderate risk assessment rating, indicating the importance of its role in managing water resources in the region.
Water resource and climate enthusiasts will appreciate the significance of Wendy Hill Upper Lake Dam in safeguarding the local area from flood events. With its strategic location along the Poplar Branch Waterway, the dam stands as a testament to the collaborative efforts between private owners and state regulatory agencies in managing water resources and reducing flood risks. As a vital piece of infrastructure in Mississippi, Wendy Hill Upper Lake Dam showcases the importance of proactive water management strategies in the face of changing climate patterns and increasing environmental challenges.

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.
