Summary
The dam stands at a height of 10 feet with a hydraulic height of 8 feet, primarily serving as an Earth type dam with a Buttress core design. It has a storage capacity of 50 acre-feet, with a normal storage level of 40 acre-feet, and covers a length of 1970 feet.
Managed by the Mississippi Department of Environmental Quality, Weir Lagoon Dam is state-regulated, permitted, inspected, and enforced to ensure its safety and compliance with regulations. The dam's spillway type is uncontrolled, with a low hazard potential and a moderate risk assessment rating. While it has not been given a condition assessment rating, the dam is considered to meet guidelines for emergency action plans, although specific details regarding preparedness and risk management measures are not provided.
Overall, Weir Lagoon Dam serves as a vital structure for water resource management in the area, providing storage capacity and flood control measures while being monitored and regulated by state authorities. As a point of interest for water resource and climate enthusiasts, the dam's design and operational details offer valuable insights into the infrastructure that plays a crucial role in maintaining water quality and quantity 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.
