Summary
Completed in 1961, this earth dam with a height of 27 feet plays a vital role in flood risk reduction, serving as a barrier to protect the surrounding community from potential disasters. With a storage capacity of 300 acre-feet and a drainage area of 0.74 square miles, this dam is regulated by the Mississippi Department of Environmental Quality to ensure its safety and effectiveness.
The Hotophia Creek Watershed Structure Y-10a-47a Dam, situated along TR- Hotophia Creek, is designed with a buttress core and a soil foundation, emphasizing its stability and resilience against water pressures. Despite being classified as having a low hazard potential, the dam is subject to regular inspections, state regulations, and enforcement to maintain its structural integrity and functionality. While its condition is currently not rated, the dam serves as a critical infrastructure for flood management in the region, mitigating risks and safeguarding the community from potential disasters.
As one of the key flood risk reduction structures in the area, the Y-10a-47a Dam plays a vital role in managing water resources and protecting the local environment. With its uncontrolled spillway and outlet gates, the dam ensures the controlled release of water during peak flow periods, reducing the risk of flooding downstream. While the dam's hazard potential is considered low, ongoing risk assessments and management measures are in place to address any potential vulnerabilities and maintain its operational effectiveness in the face of changing climate 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.
