Summary

Situated on Bayou Des Cannes, this private-owned earth dam stands at a height of 18 feet with a hydraulic height of 16 feet and a length of 5400 feet. The dam boasts a storage capacity of 1359 acre-feet, providing a serene surface area of 151 acres for outdoor enthusiasts to enjoy.

Managed by the Louisiana Department of Transportation and Development, Mauriaun Lake Dam has been inspected regularly, with its last assessment in May 2019 rating its condition as fair and its hazard potential as low. Despite its moderate risk assessment, the dam is equipped with an uncontrolled spillway and lacks outlet gates, indicating a lower risk of potential emergencies. Its strategic location near Eunice and its historical significance make Mauriaun Lake Dam a noteworthy landmark for water resource and climate enthusiasts to explore and appreciate.

With its sturdy construction and commitment to safety measures, Mauriaun Lake Dam stands as a testament to responsible water resource management in Louisiana. As a hub for recreational activities and a picturesque site along Bayou Des Cannes, this earth dam continues to provide both environmental and social benefits to the local community. For those passionate about water resources and climate conservation, Mauriaun Lake Dam offers a fascinating insight into the intersection of infrastructure, nature, and human recreation in a unique Louisiana setting.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
