Summary
Completed in 2013, this buttress dam stands at a height of 29 feet and has a storage capacity of 315 acre-feet, with a normal storage level of 236 acre-feet. The dam covers a surface area of 25 acres and has a drainage area of 0.04 square miles.
With a low hazard potential and a moderate risk assessment rating of 3, Topashaw Farms Dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections, permitting, and enforcement. The dam features an uncontrolled spillway and has a maximum discharge rate of 242 cubic feet per second. Despite not being rated for its condition, the dam meets safety guidelines and is equipped to handle emergencies, although specific emergency action plans and risk management measures are not explicitly stated.
Overall, Topashaw Farms Dam serves as a crucial water resource infrastructure in the region, ensuring a stable water supply for irrigation purposes. Its construction reflects a commitment to sustainable water management practices and highlights the importance of maintaining and regulating dams to mitigate potential risks and ensure the safety of surrounding communities and ecosystems. As a key component of the local water infrastructure, Topashaw Farms Dam plays a vital role in supporting agricultural activities and environmental sustainability in the area.

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.
