Giverney Dam dam
Giverney Dam
Giverney Dam, located in Charlotte, North Carolina, is a privately owned earth dam primarily used for recreation purposes. The dam stands at a hydraulic height of 18 feet and a structural height of 22.3 feet, with a total length of 180 feet. It harnesses the waters of Mcmullen Creek-Tr for a maximum storage capacity of 26.8 acre-feet and covers a surface area of 3 acres. Despite its modest size, the dam's hazard potential is rated as high, highlighting the importance of regular inspections and maintenance.
Managed by the North Carolina Dam Safety Program, Giverney Dam is subject to state regulation, permitting, inspection, and enforcement. The dam's condition assessment as of December 2020 was deemed fair, indicating a need for ongoing monitoring and potential improvements to ensure its long-term safety and functionality. With a history of regular inspections and a commitment to maintaining compliance with safety guidelines, Giverney Dam serves as a vital recreational asset within the Mecklenburg community.
As a key feature within the Mcmullen Creek-Tr watershed, Giverney Dam plays a crucial role in managing water resources and providing recreational opportunities for residents and visitors alike. Its location in a high-risk area underscores the importance of proactive risk management measures and emergency preparedness. By staying vigilant and implementing necessary safeguards, Giverney Dam can continue to fulfill its dual functions of water regulation and recreation while safeguarding the surrounding environment and communities from potential hazards.
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 Giverney Dam
Where does the data for Giverney 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.
