Summary
The dam, primarily constructed for purposes other than flood control or water supply, stands at a height of 10 feet and has a storage capacity of 80 acre-feet. With a low hazard potential and a moderate risk assessment rating, this Earth-type dam with a buttress core serves as a crucial infrastructure in the area.
Despite not having a designated year of completion or a detailed inspection history, Newton Lagoon Dam is equipped with an uncontrolled spillway and is deemed to meet regulatory guidelines. The dam's risk management measures and emergency preparedness status remain unassessed, highlighting potential areas for improvement in ensuring the safety and functionality of the structure. Located within the Vicksburg District and with Congressman Michael Guest as the representative, the dam plays a vital role in managing water resources in the region.
As water resource and climate enthusiasts closely monitor the state of dams and their impact on the environment, Newton Lagoon Dam serves as a focal point for ongoing assessment and risk mitigation efforts. With its unique characteristics and regulatory oversight, the dam underscores the importance of maintaining infrastructure resilience in the face of evolving climate challenges. As stakeholders continue to prioritize dam safety and emergency preparedness, Newton Lagoon Dam stands as a testament to the critical role of sustainable water management practices in safeguarding communities and ecosystems.

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.
