Summary
Constructed in 1958 by the USDA NRCS, this earth dam stands at a height of 36 feet and serves the primary purpose of flood risk reduction along TR- BIG SPRING CREEK. With a storage capacity of 163 acre-feet, this structure plays a crucial role in managing water resources in the area.
Managed by the local government and regulated by the Mississippi Department of Environmental Quality, this dam is classified as having a low hazard potential with a moderate risk assessment. Despite its age, the dam remains in good condition and has not undergone any major modifications over the years. While not rated for its current condition, the structure is inspected, permitted, and enforced regularly to ensure its continued functionality in protecting the surrounding communities from potential flooding events.
For water resource and climate enthusiasts, the Big Spring Subwatershed Structure R-7-14 Dam represents a key component in the local flood risk reduction strategy. Situated in a picturesque setting in Waites, Mississippi, this earth dam is a testament to sound infrastructure design and management practices. As the area continues to face the challenges of climate change and water resource management, structures like this will play an increasingly important role in safeguarding communities and ecosystems from the impacts of extreme weather events.

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.
