Summary
The dam, standing at 9 feet high and spanning 486 feet in length, holds a maximum storage capacity of 105 acre-feet. The lake covers an area of 14 acres and is fed by the Bailey Branch river. Despite its low hazard potential and fair condition assessment, the dam is regulated by the Louisiana Department of Transportation and Development, ensuring the safety and maintenance of this water resource.
With its picturesque surroundings and ample recreational opportunities, Mirror Lake serves as a popular destination for water enthusiasts in Tangipahoa County. Boasting a spillway width of 86 feet and a maximum discharge capacity of 803 cubic feet per second, the lake provides a tranquil escape for fishing, boating, and other leisure activities. The dam's earth construction, supported by buttress and stone cores, underscores its resilience and structural integrity in the face of Louisiana's climate challenges.
As climate change continues to impact water resources across the country, Mirror Lake stands as a testament to sustainable water management practices. With a moderate risk assessment score and regular inspections since 2016, the dam serves as a vital asset in the region's water infrastructure. As water resource and climate enthusiasts alike flock to this serene oasis, Mirror Lake remains a symbol of natural beauty and human ingenuity in the face of environmental uncertainty.

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.
