Summary
The earth dam has a height of 20 feet and a hydraulic height of 18 feet, providing a storage capacity of 130 acre-feet. With a spillway width of 40 feet and a low hazard potential, the dam is considered to be in fair condition as of the last assessment in August 2018.
The primary purpose of Port Hudson Lake No 3 is recreation, offering a surface area of 13 acres for water enthusiasts to enjoy. Despite its moderate risk assessment, the dam has not been modified in recent years and lacks emergency action plans as of the latest data update in April 2021. The lake is situated near Cooper Bayou and is part of Congressional District 06, Louisiana, making it a valuable water resource for the local community.
As a site with historical significance and potential for outdoor activities, Port Hudson Lake No 3 serves as a reminder of the importance of maintaining and monitoring water infrastructure for both safety and enjoyment. Climate and water resource enthusiasts can appreciate the unique characteristics of this dam and the efforts required to ensure its continued functionality in the face of changing environmental conditions.

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.
