Summary
Completed in 1967, this earth dam stands at a height of 25 feet and spans a length of 1250 feet, creating a reservoir with a normal storage capacity of 990 acre-feet. The dam is situated on Middle Tulip Creek within the Tupelo city limits and is regulated by the Mississippi Department of Environmental Quality.
Despite its important role in providing recreational opportunities and water storage, Lake Piomingo Dam has been classified as having a high hazard potential and an unsatisfactory condition assessment. The dam's emergency action plan was last revised in 2018, and regular inspections are conducted to ensure public safety. With a moderate risk assessment rating, it is crucial for authorities to implement effective risk management measures to address any potential issues that may arise.
The dam's spillway operates on an uncontrolled basis, and the surrounding area is at risk of inundation in case of a breach. With a maximum discharge capacity of 233 cubic feet per second, it is essential for stakeholders to stay vigilant and prepared for any emergency situations. As water resource and climate enthusiasts, it is important to monitor the condition of Lake Piomingo Dam and advocate for proactive measures to ensure the safety and sustainability of this vital infrastructure.

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.
