Summary
This earth dam with a buttress core stands at a height of 12 feet, providing a storage capacity of 105 acre-feet. While the dam is considered to have a low hazard potential, it is regulated by the Mississippi Department of Environmental Quality, ensuring that state permitting, inspection, and enforcement measures are in place.
Despite not having a designated dam type, Morrow Lake Number 3 Dam serves as a vital recreational resource in the area, offering opportunities for boating, fishing, and other water-related activities. The dam's uncontrolled spillway and moderate risk assessment highlight the importance of ongoing risk management and emergency preparedness. Although the dam's condition is currently not rated, its presence contributes to the overall water landscape in Rankin County, providing both enjoyment and potential challenges to be addressed by local authorities.
As an integral part of the water infrastructure in Mississippi, Morrow Lake Number 3 Dam is a key feature in the region's water resource management. With a focus on recreation and a moderate risk level, this dam underscores the importance of balancing human enjoyment with safety and environmental stewardship. As climate change continues to impact water resources, maintaining and monitoring structures like Morrow Lake Number 3 Dam will be crucial for ensuring sustainable water usage and protection of surrounding ecosystems.

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.
