Summary
Built in 1966 by the USDA NRCS, this earthen dam stands at a height of 38 feet and serves primarily for flood risk reduction along the TR- Pigeon Roost river or stream. With a storage capacity of 209 acre-feet, this dam plays a crucial role in managing water flow and protecting the surrounding areas from potential flooding events.
The dam is regulated and inspected by the Mississippi Department of Environmental Quality, ensuring that it meets safety and environmental standards. Despite being classified with a low hazard potential, the dam's risk assessment is moderate, highlighting the importance of regular maintenance and monitoring. While the condition of the dam is currently not rated, its purpose and design as well as the involvement of federal agencies like the Natural Resources Conservation Service demonstrate a commitment to water resource management and climate resilience in the region.
Overall, the Pigeon Roost Watershed Structure Y-5-111 Dam is an essential infrastructure for flood risk reduction in the area, with a focus on protecting communities and natural habitats from potential water-related disasters. Its location, design, and regulatory oversight underscore the importance of sustainable water resource management and climate adaptation strategies in the face of changing environmental 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.
