Summary
The dam, primarily used for recreation, stands at a height of 16 feet and has a storage capacity of 100 acre-feet. It is classified as an earth dam with a buttress core and soil foundation, providing essential flood control measures for the TR- George Branch river.
Managed by the Mississippi Department of Environmental Quality, Earl Pinham Lake Dam is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. The dam's spillway is uncontrolled, and the outlet gates are also uncontrolled, highlighting the need for ongoing monitoring and risk assessment. The dam's hazard potential is currently labeled as undetermined, with a moderate risk level assigned.
Water resource and climate enthusiasts will appreciate the strategic importance of Earl Pinham Lake Dam in managing water flow and protecting the surrounding area from potential flooding events. As a private-owned structure, the dam plays a crucial role in preserving the ecological balance of the Pearl River in Mississippi. With its historical significance and ongoing state oversight, Earl Pinham Lake Dam remains a key player in the region's water management efforts, embodying the intersection of human infrastructure and natural resource conservation.

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.
