Summary
Built in 1972, this earth dam structure stands 13 feet tall with a length of 970 feet, providing a storage capacity of 143 acre-feet and a surface area of 22 acres. The dam is regulated and inspected by the Louisiana Department of Transportation and Development to ensure its safety and compliance with state regulations.
Despite its low hazard potential, the Eatman Estate dam is assessed to be in poor condition as of November 2017, with a moderate risk level of 3. The dam has an uncontrolled spillway and a maximum discharge capacity of 1715 cubic feet per second, serving a drainage area of 2 square miles. The estate is situated along the TR-Wallace Creek, within the Vicksburg District, and is overseen by the primary owner, Dr. WC Platt, with the assistance of state regulators for permitting, inspection, and enforcement activities.
As a significant water resource in De Soto, Louisiana, the Eatman Estate showcases the intersection of human intervention with natural elements, providing essential services while also posing challenges for maintenance and risk management. With its historical significance and ongoing operational needs, the estate offers a unique opportunity for water resource and climate enthusiasts to engage with the complexities of dam infrastructure and environmental stewardship in a dynamic landscape.

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.
