Summary
Designed by the USDA NRCS and completed in 1962, this dam serves the primary purpose of flood risk reduction along the TR- Cypress Creek river or stream. With a dam height of 27 feet and a storage capacity of 469 acre-feet, this structure plays a crucial role in mitigating the impact of heavy rainfall and potential flooding in the area.
Managed by the Mississippi Department of Environmental Quality, this dam is state-regulated and undergoes regular inspections and enforcement to ensure its safety and effectiveness. Despite being classified as having a low hazard potential, a moderate risk assessment rating of 3 highlights the importance of ongoing risk management measures. The dam features an uncontrolled spillway and outlet gates, providing a means of controlled water release during high water events. With its strategic location and design, the Cypress Creek Watershed Structure Lt-14a-04 Dam stands as a key component in the region's water resource and climate resilience efforts.
Enthusiasts of water resources and climate will find the Cypress Creek Watershed Structure Lt-14a-04 Dam to be a fascinating example of infrastructure designed to address flood risk and protect surrounding communities. Its collaboration between local government ownership, federal design by the USDA NRCS, and state regulation by the Mississippi Department of Environmental Quality showcases a comprehensive approach to water management. As climate change continues to impact precipitation patterns, structures like Lt-14a-4 play a vital role in safeguarding against potential flooding events and ensuring the long-term sustainability of water resources in the area.

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.
