Summary
Built in 1960 by the USDA NRCS, this dam plays a crucial role in flood risk reduction along the TR-PRUILL CREEK. With a height of 18 feet and a storage capacity of 242 acre-feet, the dam is designed to mitigate potential hazards and manage water resources effectively in the region.
Despite being categorized as having a low hazard potential, the Bogue Watershed Structure Y-30-020 Dam is regulated, inspected, and enforced by the Mississippi Department of Environmental Quality. The dam's primary purpose is flood risk reduction, and it serves as a vital infrastructure for the local community. Although currently rated as "Not Rated" for condition assessment, the dam continues to play a significant role in water resource management and climate resilience efforts in the area.
With a moderate risk assessment rating of 3, there is a need for ongoing risk management measures to ensure the safety and functionality of the Bogue Watershed Structure Y-30-020 Dam. As water resource and climate enthusiasts, it is essential to monitor the dam's condition closely, implement necessary maintenance and improvements, and collaborate with relevant agencies to enhance the resilience of this critical infrastructure. By staying informed and engaged, we can contribute to the sustainable management of water resources and climate adaptation initiatives in the Bogue Watershed region.

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.
