Summary
Jackson Dam, located in Grant, Louisiana, is a privately owned structure on Fouchmiah Creek with a primary purpose of recreation. Built in 1951, this earth dam stands at 17 feet tall and spans 300 feet in length, offering a storage capacity of 70 acre-feet. The dam is regulated by the Louisiana Department of Transportation and Development, with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite having a low hazard potential and a moderate risk assessment rating, the condition of E.C. Jackson Dam is currently listed as "Not Rated" as of the last inspection in March 2018. The dam features an uncontrolled spillway with a width of 30 feet, allowing for a maximum discharge of 250 cubic feet per second. While there are no associated locks, the dam provides recreational opportunities for visitors in the area, with a surface area of 14 acres and a drainage area of 1 square mile.
Water resource and climate enthusiasts will find E.C. Jackson Dam to be a unique and important structure within the region, offering both recreational benefits and necessary water storage capacity. With state regulation and oversight in place, the dam continues to serve its purpose while maintaining a focus on safety and risk management. As one of the key features along Fouchmiah Creek, this earth dam plays a significant role in the local ecosystem and water management efforts in Louisiana.

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.
