Nab Drennen Dams dam
Nab Drennen Dams
Nab Drennen Dams, located in Greene, Alabama, along the Tombigbee River, is a private recreational facility completed in 1955. The earth dam stands at a structural height of 20 feet, with a hydraulic height of 17 feet and a length of 400 feet. The dam has a storage capacity of 54 acre-feet and a maximum discharge of 680 cubic feet per second. Despite being privately owned, the dam is not regulated by the state and has a low hazard potential.
The surrounding area offers opportunities for outdoor activities such as boating, fishing, and hiking, making Nab Drennen Dams a popular destination for water resource and climate enthusiasts. The dam's peaceful setting, coupled with its historical significance and recreational amenities, attracts visitors seeking a tranquil escape in nature. While the dam's condition is currently not rated, it remains a safe and enjoyable spot for individuals looking to unwind and reconnect with the environment.
With its rich history and scenic location, Nab Drennen Dams serves as a reminder of the importance of preserving and appreciating our water resources. As climate change continues to impact our environment, it is crucial to protect and maintain structures like this dam to ensure that future generations can continue to enjoy and benefit from its recreational offerings. Whether exploring the surrounding area or simply enjoying a quiet moment by the water, Nab Drennen Dams offers a unique and memorable experience for all who visit.

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.
Plan around the weather

About Nab Drennen Dams
Where does the data for Nab Drennen Dams 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.
