Summary
The dam, primarily constructed from earth and stone materials, stands at a height of 21 feet and has a capacity for storing 116 acre-feet of water. With a surface area of 11 acres and a drainage area of 0.06 square miles, the dam serves multiple purposes including fire protection and stock maintenance in addition to its primary function as a fish and wildlife habitat.
Managed by the Louisiana Department of Transportation and Development, the dam at Port Hudson Lake No 2 is regulated, inspected, and enforced by state authorities. Despite having a low hazard potential and a fair condition assessment, the dam poses a moderate risk, with an emergency action plan still pending preparation. The spillway, with a width of 75 feet, is uncontrolled, and the dam has a maximum discharge capacity of 834 cubic feet per second. The location along TR - Cooper Bayou and proximity to Congressional District 06 make this site an important water resource for the region.
Overall, Port Hudson Lake No 2 is a significant water resource in Louisiana, providing valuable habitat for fish and wildlife. Its construction and management demonstrate a commitment to environmental stewardship and safety, albeit with some room for improvement in terms of risk assessment and emergency preparedness. For water resource and climate enthusiasts, this site offers an intriguing case study in dam design, regulation, and maintenance within the context of a changing climate and evolving water management practices.

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.
