Summary
Completed in 2000, this earth dam stands at a height of 23.7 feet and has a length of 550 feet. It has a storage capacity of 164 acre-feet and covers a surface area of 12.5 acres. The dam is regulated by the Mississippi Department of Environmental Quality and is inspected, permitted, and enforced by state authorities.
Despite being classified as having a low hazard potential, Buchanan Lake Dam is considered to have a moderate risk level. While the condition assessment is not rated, the dam has not been modified in recent years and does not have any associated structures or outlet gates. The spillway type is uncontrolled, with a maximum discharge capacity of 21 cubic feet per second. The dam's risk management measures, emergency action plan, and inundation maps are not readily available, suggesting a need for improved emergency preparedness and risk mitigation strategies.
Water resource and climate enthusiasts may find Buchanan Lake Dam an interesting case study for its recreational significance and state-regulated status. With its location in Rankin County, Mississippi, and under the jurisdiction of the Mobile District of the US Army Corps of Engineers, this dam serves as a focal point for understanding the intersection of water management, environmental regulations, and infrastructure development in the region. Further research and monitoring of Buchanan Lake Dam could provide valuable insights into mitigating risks and ensuring the safety and sustainability of water resources in the area.

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.
