Cornish Creek Reservoir Dam dam
Cornish Creek Reservoir Dam
Cornish Creek Reservoir Dam in Newton, Georgia, is a vital water supply structure designed by WELKER & ASSOC. and completed in 1991. The dam stands at a height of 46.5 feet and has a storage capacity of 18,400 acre-feet, serving the primary purpose of water supply for the region. With a high hazard potential but a satisfactory condition assessment as of March 2019, the dam is under state regulation and inspection by the GA-SAFE DAMS PROGRAM, ensuring its safety and reliability for the community.
Located on Cornish Creek, this Earth-type dam with a buttress core spans 1600 feet and covers a surface area of 820 acres, drawing from a drainage area of 24.73 square miles. While the dam features uncontrolled spillways and outlet gates, it operates within state permitting and enforcement guidelines, emphasizing the importance of effective risk management measures. The dam's moderate risk assessment rating highlights the need for continued monitoring and maintenance to uphold its crucial role in providing water resources for the area.
Managed by the Local Government, Cornish Creek Reservoir Dam plays a key role in water supply infrastructure for Newton, Georgia. Although its hazard potential is deemed high, the dam's current condition is deemed satisfactory, thanks to regular inspections and enforcement by state regulatory agencies. With its completion in 1991, this vital structure continues to serve the community, underscoring the importance of responsible stewardship and risk management to ensure the safety and reliability of water resources in the region.
Dam data reference
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 Cornish Creek Reservoir Dam
Where does the data for Cornish Creek Reservoir 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 High 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.
