Summary
This earth dam with a buttress core stands at a height of 13 feet and has a storage capacity of 293 acre-feet. The dam is situated on the UNT of Organ Creek and is owned and regulated by the local government, with oversight from the Mississippi Department of Environmental Quality.
Despite being classified as having a low hazard potential, the dam is considered to have a moderate risk level. It has not been inspected or rated for its condition, and there is no Emergency Action Plan (EAP) in place for potential incidents. While the structure has not been modified over the years, it lacks detailed risk management measures and inundation maps for emergency preparedness. The dam's spillway is uncontrolled, with no outlet gates, and its overall risk assessment suggests a need for improved safety protocols and monitoring.
For water resource and climate enthusiasts, the Perry Creek Watershed Structure Y-19c-1 Dam presents an intriguing case study in dam infrastructure management. With its historical significance and ongoing regulatory oversight, the dam offers opportunities for research and analysis on flood risk reduction strategies and emergency response preparedness. As the dam's risk level is assessed as moderate, there is a pressing need for further evaluation and potential updates to ensure the safety and resilience of the structure in the face of changing climate patterns and potential natural disasters.

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.
