Summary
This earth dam with a buttress core stands at a height of 11 feet and has a storage capacity of 715 acre-feet. While it serves a primary purpose of "Other," it plays a vital role in managing wastewater and ensuring water quality in the region.
With a low hazard potential and a moderate risk assessment rating, the Columbia Sewage Lagoon Dam is closely monitored for its structural integrity and safety measures. Despite being uncontrolled, the dam's spillway type indicates a level of preparedness for managing excess water flow. While not currently rated for condition assessment, the dam's risk management measures are in place to mitigate any potential issues and ensure the safety of the surrounding community and environment.
For water resource and climate enthusiasts, the Columbia Sewage Lagoon Dam presents an opportunity to study the intersection of infrastructure, water management, and environmental regulations. Its location in Marion County, Mississippi, within the Vicksburg District, showcases the importance of sustainable water practices and the role of local and state agencies in protecting water resources. As efforts continue to monitor and maintain the dam, it serves as a reminder of the ongoing commitment to safeguarding water quality and ensuring the resilience of critical infrastructure in the face of changing climatic conditions.

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.
