Summary
Built in 1974 by the USDA NRCS, this earth dam serves primarily for flood risk reduction along the TR- Murry Creek. With a height of 30 feet and a storage capacity of 308 acre-feet, the dam plays a significant role in managing water flow and protecting the surrounding areas from potential flooding events.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, the dam boasts a low hazard potential and a moderate risk assessment rating. Although the condition assessment is currently listed as "Not Rated", the dam continues to operate effectively, with uncontrolled spillways and outlets to manage excess water during high-flow events. Its strategic location and design make it a key component in the water resource infrastructure of the region, ensuring the safety and well-being of nearby communities.
As an essential structure for water resource management, Murray Creek Watershed Structure Y-13a-4 Dam stands as a testament to the importance of proactive flood risk reduction measures. With a history of service dating back to the 1970s, the dam continues to play a vital role in safeguarding the local area from potential water-related hazards. As climate change continues to impact weather patterns and water availability, structures like Y-13a-4 become increasingly crucial for maintaining a resilient and sustainable water resource system in Mississippi.

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.
