Summary
The dam stands at a height of 30 feet, with a hydraulic height of 20 feet, and a length of 2200 feet. The reservoir created by the dam has a storage capacity of 2860 acre-feet and serves as a popular spot for outdoor activities in the region.
Despite its recreational value, the dam is classified as having a high hazard potential and poor condition assessment. Regular inspections are conducted by the Mississippi Department of Environmental Quality to ensure its safety and compliance with regulatory standards. The dam's spillway type is uncontrolled, and it has a maximum discharge capacity of 345 cubic feet per second.
Water resource and climate enthusiasts visiting Roosevelt State Park Lake Dam can appreciate the engineering feat that went into its construction and the importance of proper maintenance to ensure public safety and the preservation of the surrounding environment. As a key piece of infrastructure in the area, the dam plays a crucial role in providing recreational opportunities while also managing water resources effectively.

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.
