Summary
The dam, classified as an earth dam with buttress core type, stands at a height of 12 feet and has a storage capacity of 120 acre-feet. The dam's spillway type is uncontrolled, with a low hazard potential and a moderate risk assessment rating of 3.
Managed by the Mississippi Department of Environmental Quality, the dam is state-regulated, inspected, and enforced to ensure safety and compliance with regulatory standards. Despite not having a condition rating, the dam's risk management measures are in place to mitigate any potential hazards. While the dam's associated structures and emergency preparedness details are not specified, Trullys Lake Dam remains a vital recreational resource for the local community in Mississippi.
With its picturesque location and crucial role in providing recreational opportunities, Trullys Lake Dam serves as a significant water resource in the area. Its careful regulation and moderate risk assessment underscore the importance of maintaining infrastructure for both safety and enjoyment. As water resource and climate enthusiasts, understanding the details of Trullys Lake Dam's structure and management can deepen appreciation for the intersection of human-made structures with environmental stewardship in supporting sustainable water management practices.

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.
