Summary
With a height of 29 feet and a storage capacity of 882 acre-feet, this dam plays a crucial role in managing the waters of TR- Cypress Creek and Wolf Creek. Despite its low hazard potential, the dam is regulated, permitted, inspected, and enforced by the Mississippi Department of Environmental Quality, ensuring its structural integrity and functionality.
The Lt-14a-12 Dam features an uncontrolled spillway and outlet gates, indicating its design to handle excess water flow during times of heavy rainfall or flooding. While the dam is currently rated as not assessed for condition, its risk assessment is moderate (3), highlighting the importance of ongoing monitoring and maintenance. The dam's association with flood risk reduction underscores its critical role in protecting the surrounding area from potential water-related disasters, making it a key structure in the Cypress Creek watershed.
Managed by local government authorities, the Lt-14a-12 Dam is an essential part of the water resource infrastructure in Lafayette County, Mississippi. With its substantial storage capacity and flood risk reduction capabilities, this earth dam serves as a vital component in the overall water management strategy for the region. As climate change continues to impact weather patterns and increase the frequency of extreme events, structures like the Lt-14a-12 Dam play a crucial role in safeguarding communities and ecosystems from the potential impacts of flooding and water-related disasters.

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.
