Summary
Built in 1955 by the USDA NRCS, this privately-owned earth dam stands at a height of 12 feet and has a storage capacity of 105 acre-feet. Despite its modest size, the dam is regulated by the Mississippi Department of Environmental Quality and undergoes regular inspections to ensure its safety and compliance with state regulations.
With a low hazard potential and a moderate risk assessment rating, Pat Mcdonald Lake Dam is considered a relatively safe structure. Its uncontrolled spillway and outlet gates contribute to its low hazard potential, while its condition assessment remains unrated. The dam's primary purpose is for recreation, attracting visitors to the Indian Reservation area for outdoor enjoyment. However, without a current inspection date or emergency action plan in place, there may be room for improvement in the dam's risk management and emergency preparedness measures.
As a key feature along the TR-Pearl River, Pat Mcdonald Lake Dam stands as a testament to the importance of water resource management and climate resilience. With its history of construction and ongoing state regulation, the dam offers a glimpse into the intersection of human ingenuity and environmental stewardship in safeguarding our water resources for generations to come.

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.
