Cherokee County Raw Water Storage Lake Dam dam
Cherokee County Raw Water Storage Lake Dam
Located in Ball Ground, Georgia, the Cherokee County Raw Water Storage Lake Dam serves as a crucial water supply structure for the local community. Constructed in 1986, this earth dam stands at a height of 53 feet and has a maximum storage capacity of 43.8 acre-feet, with a normal storage level of 22 acre-feet. The dam spans a length of 630 feet and features an uncontrolled spillway, emphasizing its primary purpose of water supply.
Designed by WELKER & ASSOC., the Cherokee County Raw Water Storage Lake Dam is regulated by the state jurisdiction and undergoes regular inspections, with the last one conducted in May 2019. Despite being categorized as having a low hazard potential, the dam's risk assessment is rated as moderate (3), indicating a need for ongoing monitoring and risk management measures. The dam has not been rated for its condition assessment, and additional emergency preparedness measures such as an Emergency Action Plan (EAP) are not currently in place.
Enthusiasts interested in water resources and climate in Cherokee County, Georgia, will find the Cherokee County Raw Water Storage Lake Dam a notable structure contributing to the region's water supply infrastructure. With its strategic location and functional design, the dam plays a vital role in ensuring water availability for the community while also highlighting the importance of regular inspections and risk management practices for maintaining dam safety and resilience in the face of changing environmental conditions.

About Cherokee County Raw Water Storage Lake Dam
Where does the data for Cherokee County Raw Water Storage 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 below 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.

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.
