Summary
With a primary purpose of recreation, this earth dam with a buttress core stands at a height of 22 feet and has a storage capacity of 193 acre-feet. The dam, which has a low hazard potential and moderate risk assessment, features an uncontrolled spillway and covers a surface area of 16 acres.
Managed by the Vicksburg District of the US Army Corps of Engineers, the Ridgway Management Lake Dam has not been rated for its condition assessment. While it has not undergone recent inspections and lacks certain emergency preparedness measures, the dam is considered to have moderate risk and is regulated by the state of Mississippi. Despite its recreational focus, the dam's risk management measures and overall safety preparedness remain areas of concern that may require attention in the future.
As a critical water resource in the area, enthusiasts interested in water management and climate impacts should monitor the Ridgway Management Lake Dam for any updates on its inspection frequency, condition assessment, and emergency action plan. The dam's role in providing recreational opportunities and storage capacity for water resources underscores the importance of maintaining its structural integrity and safety standards to ensure the well-being of surrounding communities and the environment.

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.
