Summary
Built in 1959 by the Louisiana Department of Public Works, this earth dam spans 1,700 feet and stands at a height of 28 feet. The primary purpose of the dam is for recreation and other uses, with a capacity to store up to 100,000 acre-feet of water from the Bayou Cocodrie.
With a hazard potential rated as high and a fair condition assessment, the dam is regularly inspected by the Louisiana Department of Transportation and Development. The last inspection in December 2020 deemed the structure to be in fair condition. Despite some modifications in 1986, including structural enhancements, the dam remains a vital component for water resource management and recreational activities in the area.
Although there are currently no associated structures or locks, the dam features an uncontrolled spillway and slide gates for water release. With a moderate risk assessment rating, the Bayou Cocodrie Dam serves as a critical infrastructure for managing water levels, ensuring public safety, and supporting various recreational activities in the region.

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.
