Green Lake Dam dam
Green Lake Dam
Green Lake Dam, located in Elizabethtown, North Carolina, is a private-owned structure with a primary purpose of recreation. Completed in 1960, this earth dam stands at a structural height of 52 feet and has a hydraulic height of 10 feet. The dam has a storage capacity of 572 acre-feet and covers a surface area of 150 acres, offering a serene spot for water enthusiasts and outdoor lovers to enjoy.
Managed by the NC Department of Environmental Quality's Dam Safety Program, Green Lake Dam is regulated, permitted, inspected, and enforced by state agencies to ensure its safety and compliance with regulations. The dam has a low hazard potential and is currently in fair condition, last assessed in June 2017. Despite its age, the dam continues to provide a safe and enjoyable recreational space for locals and visitors alike, contributing to the conservation and preservation of water resources in the area.
With its peaceful surroundings and recreational opportunities, Green Lake Dam on the Cape Fear River-Os is a vital piece of infrastructure that not only enhances the local ecosystem but also serves as a valuable water resource for the community. As climate and water resource enthusiasts, understanding the importance of structures like Green Lake Dam in maintaining a balance between conservation and recreation is crucial for sustainable water management practices in the region.

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.
