Summary
Constructed in 1969 by RUST Engineering Company, this dam stands at a height of 65 feet and has a length of 3700 feet, providing a storage capacity of 2080 acre-feet. The dam serves the primary purpose of water supply, with a controlled spillway type and a low hazard potential.
Despite being in fair condition as per the last assessment in September 2018, Boise Cascade Mill poses a very high risk due to its location and design characteristics. The dam is regulated and inspected by the Louisiana Department of Transportation and Development, ensuring compliance with state permitting and enforcement requirements. In case of emergencies, the dam has an Emergency Action Plan (EAP) in place, although its last revision date is unknown.
With its unique design featuring earth, buttress, and stone core types, Boise Cascade Mill stands as a critical infrastructure for water resource management in the area. Enthusiasts of water resources and climate will find this dam's history, design, and operational features intriguing, highlighting the importance of sustainable water supply systems in mitigating climate change impacts.

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.
