Summary
This earth dam with a core type of buttress serves primarily for recreational purposes and has a height of 8 feet with a storage capacity of 800 acre-feet. The dam is situated on the TR-Sunflower River and is regulated by the Mississippi Department of Environmental Quality.
Despite being classified as having a low hazard potential and a moderate risk level, the dam's condition assessment remains unrated. It features an uncontrolled spillway and outlet gates, with no associated locks present. The dam has not been modified in recent years and lacks emergency action plans or inundation maps. While the risk management measures and guidelines compliance status are not specified, the dam is subject to inspection, permitting, and enforcement by state regulatory agencies.
Water resource and climate enthusiasts interested in Tisdale Lake Dam can appreciate its unique design and purpose, as well as the regulatory framework in place to ensure its safety. The dam's location on the Sunflower River provides recreational opportunities while also highlighting the importance of proper maintenance and monitoring to mitigate potential risks. With a focus on risk assessment and management, ongoing evaluation of the dam's condition and emergency preparedness measures is crucial to safeguard the surrounding community and water resources.

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.
