Summary
Standing at a height of 33 feet with a hydraulic height of 27 feet, the dam offers a maximum storage capacity of 400 acre-feet and a normal storage level of 263.6 acre-feet. The dam spans 670 feet in length and covers a surface area of 24 acres, providing a serene setting for outdoor activities such as fishing, boating, and picnicking.
Managed by the Mississippi Department of Environmental Quality, Twin Oaks Lake Dam is regulated, inspected, and enforced by state authorities to ensure public safety and environmental compliance. While the dam's hazard potential is currently undetermined and its condition remains unrated, a moderate risk assessment has been assigned to the structure. With an uncontrolled spillway and moderate risk level, the dam serves as a vital water resource for the surrounding area, contributing to the management of the Coldwater River watershed.
Despite its limited federal involvement, Twin Oaks Lake Dam plays a crucial role in water management and recreation in the region. As a popular spot for outdoor enthusiasts and nature lovers, the dam offers a peaceful retreat amidst the beautiful Mississippi landscape. With its strategic location and essential functions, Twin Oaks Lake Dam stands as a testament to the importance of sustainable water resource management and climate-conscious infrastructure development.

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.
