Green Lake Dam dam
Green Lake Dam
Green Lake Dam in Mississippi, completed in 1978, stands as a testament to engineering prowess in the realm of water resource management. Designed by Bobby Massey, this privately-owned earth dam on Black Creek serves primarily for recreation purposes, offering a serene oasis for outdoor enthusiasts in Holmes County. With a height of 16 feet and a storage capacity of 129 acre-feet, the dam provides a tranquil surface area of 11 acres for leisure activities like fishing and boating.
Despite its uncontrolled spillway and low hazard potential, Green Lake Dam has a moderate risk assessment due to its location and structural characteristics. The Mississippi Department of Environmental Quality oversees its regulation, inspection, and enforcement to ensure public safety and environmental compliance. While the dam's condition assessment is currently not rated, its historical significance in the local landscape warrants ongoing monitoring and risk management measures for sustainable water resource utilization.
For water resource and climate enthusiasts, Green Lake Dam offers a captivating blend of natural beauty and human ingenuity. Situated in the Vicksburg District, this earth dam symbolizes the harmonious coexistence of recreational activities with environmental stewardship. As climate change impacts water availability and quality, understanding the role of structures like Green Lake Dam becomes paramount in mitigating risks and adapting to changing hydrological conditions.

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 Lake Dam
Where does the data for Green Lake 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 Low 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.
