Summary

Completed in 2017, this Earth-type dam stands at a height of 25 feet and has a storage capacity of 70 acre-feet. The reservoir spans over 7 acres with a drainage area of 7 square miles, providing crucial water management in the region.

Managed by the Louisiana Department of Transportation and Development, the reservoir is equipped with an uncontrolled spillway and needle outlet gates. Despite its low hazard potential, the dam's condition assessment indicates poor maintenance, highlighting the need for regular inspections and potential rehabilitation. The risk assessment categorizes the reservoir's risk as moderate, emphasizing the importance of implementing risk management measures to ensure the safety and longevity of this vital water resource in the area.

For water resource and climate enthusiasts, John Sessum No 2 Reservoir presents an intriguing case study in water infrastructure management. With its unique design features and operational challenges, the reservoir offers valuable insights into the complexities of maintaining and regulating water resources in a changing climate. As efforts continue to improve the dam's condition and risk management strategies, the reservoir stands as a testament to the vital role of water infrastructure in sustaining communities and ecosystems in the face of environmental uncertainties.

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.
