Green Acres Estate Lake 1 Dam dam
Green Acres Estate Lake 1 Dam
Green Acres Estate Lake 1 Dam, also known as Lower Lake Dam, is a privately owned earth dam located in Green Acres Estate, Arkansas. 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. As a focal point for recreation and leisure, this earth dam provides a picturesque backdrop for outdoor activities while also serving as a reminder of the importance of responsible water management practices in a changing climate.

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.
- 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.
- 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.
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, environmental 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.

About Green Acres Estate Lake 1 Dam
Where does the data for Green Acres Estate Lake 1 Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
