Built in 1959, this dam serves primarily for recreational purposes, offering a serene setting for water enthusiasts to enjoy various activities. With a hydraulic height of 19 feet and a structural height of 23 feet, the dam has a storage capacity of 100 acre-feet and a maximum discharge of 240 cubic feet per second.
Situated within the Memphis District, Green Acres Estate Lake 1 Dam is not regulated or permitted by the state, making it a unique and independent water resource structure in the region. Despite being unregulated, the dam is classified as having significant hazard potential, highlighting the importance of proper maintenance and monitoring. While the condition assessment is currently not rated, efforts to ensure safety and emergency preparedness, such as the development of an Emergency Action Plan, are crucial for the long-term sustainability of this recreational asset.
The dam's location in a private estate, coupled with its historical significance dating back to the late 1950s, makes Green Acres Estate Lake 1 Dam a valuable water resource for the 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.
