Summary
Constructed in 1966 by the USDA NRCS, this earth buttress dam stands at a height of 29 feet and has a storage capacity of 352 acre-feet. The dam plays a crucial role in protecting the surrounding area from flooding, particularly along the TR- Pigeon Roost and Red Banks rivers.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, the Pigeon Roost Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. Despite its moderate risk level, the dam serves as a key infrastructure for the region, ensuring the safety and security of nearby communities in times of high water levels. With its uncontrolled spillway and outlet gates, the dam continues to be a vital component in the overall water resource management strategy of the area.
For water resource and climate enthusiasts, the Pigeon Roost Dam represents a critical piece of infrastructure in the local watershed, providing flood risk reduction and water storage capabilities. As part of the broader network of dams and levees in the region, this structure plays a key role in mitigating potential flood risks and ensuring the resilience of the community. With its historical significance and ongoing regulatory oversight, the Pigeon Roost Dam stands as a testament to the importance of sustainable water management practices in the face of changing climate conditions.

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.
