Crumbley Lake Dam dam
Crumbley Lake Dam
Crumbley Lake Dam, located in Henry, Georgia, is a private earth dam with a primary purpose of recreation. Standing at a height of 29 feet and stretching 400 feet in length, the dam holds a normal storage capacity of 60 acre-feet and a total storage of 90 acre-feet. The dam overlooks Rock Branch river and covers an area of 8 acres, making it a picturesque spot for water resource and climate enthusiasts.
Despite being privately owned, Crumbley Lake Dam is subject to state jurisdiction and inspections, ensuring its safety and compliance with regulations. With a low hazard potential and a moderate risk assessment score of 3, the dam is considered to be in good condition, although it has not been formally rated. The last inspection in March 2017 revealed no immediate concerns, but regular inspections are conducted every 5 years to monitor its structural integrity and safety measures.
For those interested in exploring water resource management and climate adaptation, Crumbley Lake Dam offers a fascinating case study in recreational dam construction. Its uncontrolled spillway and outlet gates add to its unique design, while the surrounding area provides ample opportunities for outdoor activities and environmental appreciation. With a focus on risk management and safety measures, this dam serves as a valuable asset in understanding the intersection of water resources, infrastructure, and environmental stewardship.

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 Crumbley Lake Dam
Where does the data for Crumbley 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.
