Summary
The dam serves primarily for recreational purposes, offering a storage capacity of 76 acre-feet and a low hazard potential. With a height of 21 feet and an earth core type, the dam features an uncontrolled spillway and a moderate risk assessment rating of 3.
Although specific details regarding the dam's completion year, surface area, and drainage area remain undisclosed, its current condition is deemed not rated in terms of assessment. The dam's hazard potential is classified as low, indicating a stable and safe structure for recreational activities around Dedoe Lake. Despite its moderate risk level, the dam has not undergone a recent condition assessment and lacks updated emergency preparedness measures.
Water resource and climate enthusiasts intrigued by Dedoe Lake Dam can appreciate its functional design, recreational purpose, and regulatory oversight. The dam's location within the serene landscape of Greene, Mississippi, provides a valuable water resource for the community while maintaining a balanced approach to risk management.

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.
