Summary
Completed in 1981, this earth dam stands at 31 feet tall with a length of 1109 feet, providing a storage capacity of 1559 acre-feet and serving a drainage area of 3.67 square miles along the South Fork Tillatoba Creek.
Managed by the Mississippi Department of Environmental Quality, the dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation. Despite its high hazard potential, the dam's condition assessment in 2017 deemed it satisfactory, with a moderate risk rating. With uncontrolled spillways and outlet gates, this structure plays a crucial role in flood management within the region, showcasing the collaborative efforts between local governments and state agencies to safeguard water resources and mitigate climate-related risks in the area.
As a key component of the flood risk reduction infrastructure, the Tillatoba Creek Watershed Structure Y-17b-1 Dam serves as a vital resource in safeguarding the community against potential inundation events. With its strategic location and design features, this dam demonstrates the importance of proactive water resource management and climate resilience measures in ensuring the safety and well-being of residents in the face of changing environmental conditions.

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.
