Summary
Built in 1940, this earth dam stretches 2,300 feet across the Tangipahoa River, providing both recreational opportunities and flood protection to the surrounding area. With a maximum storage capacity of 16,800 acre-feet and a normal storage level of 4,930 acre-feet, the dam plays a crucial role in managing water flow and ensuring the safety of nearby communities.
Managed by the Mississippi Department of Environmental Quality, the Percy Quin State Park Dam is subject to regular inspections and enforcement measures to maintain its structural integrity. With a hazard potential rated as high and a fair condition assessment as of October 2020, the dam is closely monitored to mitigate any risks and ensure the safety of its downstream residents. Despite its age, the dam continues to serve its primary purpose of recreation, with a surface area of 550 acres offering ample space for outdoor activities and enjoyment.
The Percy Quin State Park Dam serves as a vital asset in Mississippi's water resource infrastructure, blending functionality with natural beauty in the heart of Pike County. As climate change continues to pose challenges to water management, the dam stands as a resilient structure that underscores the importance of proactive maintenance and risk management. With its strategic location and historical significance, the dam remains a focal point for water resource and climate enthusiasts seeking to understand the intersection of conservation, recreation, and infrastructure development.

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.
