Summary

The dam serves primarily for recreational purposes, providing a picturesque backdrop for water resource and climate enthusiasts to explore. With a height of 38 feet and a hydraulic height of 32 feet, the earth dam spans 800 feet and has a storage capacity of 440 acre-feet, with a normal storage level of 330 acre-feet.

The dam features an uncontrolled spillway and has a low hazard potential, with a moderate risk assessment rating. While the condition of the dam is currently not rated, it undergoes regular state inspections and enforcement to ensure its safety and functionality. Despite the dam not being under the jurisdiction of the US Army Corps of Engineers, it remains a vital component of the local water resource infrastructure, contributing to the beauty and recreational opportunities offered at Tombigbee State Park Lake.

Enthusiasts visiting Tombigbee State Park Lake Dam can appreciate its scenic surroundings and the efforts taken to manage its risk and ensure public safety. With its earth dam construction and buttress core design, the dam stands as a testament to the importance of water resource management in the state of Mississippi. As a key feature in the park's landscape, the dam invites visitors to learn more about its history, purpose, and the measures in place to maintain its integrity for future generations to enjoy.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
