Rhett Mill Dam dam
Rhett Mill Dam
Rhett Mill Dam, also known as Highland Lake or Madonna Lake, is a privately owned structure located in Hendersonville, North Carolina. Completed in 1955, this dam on King Creek serves primarily for recreational purposes and has a hydraulic height of 13.5 feet and a structural height of 16 feet. With a storage capacity of 361 acre-feet and a surface area of 23.8 acres, Rhett Mill Dam provides a tranquil setting for outdoor activities in the area.
Despite its satisfactory condition assessment as of March 2019, Rhett Mill Dam is classified as having a high hazard potential. The dam is regulated by the North Carolina Department of Environmental Quality (NCDEQ) Dam Safety Program, with regular inspections and enforcement activities ensuring its continued safety. The dam has a maximum discharge capacity of 1200 cubic feet per second and lies within the Wilmington District of the US Army Corps of Engineers jurisdiction.
Although lacking certain features like spillways and outlet gates, Rhett Mill Dam remains a vital part of the local landscape, offering both recreational opportunities and essential water resource management. As climate change impacts water resources and infrastructure, the ongoing maintenance and monitoring of dams like Rhett Mill are crucial to safeguarding communities and ecosystems in the face of changing environmental conditions.
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 Rhett Mill Dam
Where does the data for Rhett Mill 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.
