Rainbow Spring Lake Dam dam
Rainbow Spring Lake Dam
Rainbow Spring Lake Dam in Hendersonville, North Carolina, is a private earth dam primarily used for recreation purposes. This dam, located on Mud Creek-Tr, has a hydraulic height of 13 feet and a structural height of 15 feet. Its maximum storage capacity is 13 acre-feet, with a normal storage level of 7 acre-feet. The dam's hazard potential is considered high, but its condition assessment as of March 2019 was deemed satisfactory.
Managed by the NCDEQ Dam Safety Program, Rainbow Spring Lake Dam is subject to state regulation, inspection, and enforcement. The dam has a history of regular inspections, with the last assessment taking place in March 2019. Despite its high hazard potential, the dam meets safety guidelines and has an emergency action plan in place. The dam's location in the picturesque Henderson County makes it a popular spot for recreational activities such as boating, fishing, and picnicking.
Visitors to Rainbow Spring Lake Dam can enjoy a serene environment and engage in various outdoor activities while appreciating the vital role the dam plays in water resource management. As climate enthusiasts, it is important to acknowledge the significance of proper dam maintenance and regular inspections to ensure the safety and sustainability of this essential water infrastructure.
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 Rainbow Spring Lake Dam
Where does the data for Rainbow Spring 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 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.
