Summary
The dam, constructed primarily of earth and stone, stands at a height of 14 feet with a hydraulic height of 11 feet. With a storage capacity of 231 acre-feet and a surface area of 33 acres, this dam plays a crucial role in maintaining the ecological balance of the area.
Managed by the Louisiana Department of Transportation and Development (LA DOTD), Mark Dickson Dam No 2 is subject to state regulations, inspections, and enforcement to ensure its structural integrity and safety. Despite being classified as a low-hazard potential structure with a fair condition assessment, the dam poses a moderate risk due to its location and design features. However, with a spillway width of 90 feet and a maximum discharge capacity of 1448 cubic feet per second, the dam is equipped to handle potential flood events effectively.
As a vital component in the local ecosystem, Mark Dickson Dam No 2 not only supports fish and wildlife habitats but also provides recreational opportunities for the community. With its strategic location on TR - Loggy Bayou and its contributions to water resource management, this dam stands as a testament to the importance of sustainable infrastructure in the face of changing climate conditions.

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.
