Summary
Built in 1985, this Earth-type dam boasts a height of 20 feet and a length of 2600 feet, with a storage capacity of 244 acre-feet and a surface area of 24.4 acres. The dam, situated along TR. MUNDY BAYOU, is regulated by the Louisiana Department of Transportation and Development, ensuring proper permitting, inspection, and enforcement protocols are in place.
With a low hazard potential and fair condition assessment, the Cleco Ash Pond Dam is equipped with an uncontrolled spillway and outlet gates. Despite its moderate risk assessment rating, emergency preparedness measures such as an Emergency Action Plan (EAP) have yet to be fully developed. The dam's inspection frequency of 5 years ensures ongoing monitoring, with the last assessment conducted in September 2019. While the risk level is deemed manageable, proactive risk management strategies are recommended to address any potential hazards.
In the event of an emergency, the Cleco Ash Pond Dam's moderate risk level necessitates the development of comprehensive risk management measures. With its strategic location and significance in tailings management, the dam serves as a crucial component of water resource infrastructure in the De Soto area. As water resource and climate enthusiasts, understanding the Cleco Ash Pond Dam's design, purpose, and regulatory framework is essential for appreciating its role in safeguarding the local environment and community.

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.
