Forty Niner Lake Dam dam
Forty Niner Lake Dam
Nestled in the picturesque Greenville, South Carolina, Forty Niner Lake Dam stands as a testament to engineering excellence and environmental stewardship. Built in 1960, this private dam serves primarily for recreational purposes, offering a serene oasis for water resource and climate enthusiasts to enjoy. With a structural height of 43 feet and a length of 486 feet, the dam holds a maximum storage capacity of 83 acre-feet, providing a tranquil surface area of 5 acres for visitors to explore.
Despite its low hazard potential, the dam's condition assessment reflects a poor rating, signaling the need for maintenance and potential improvements to ensure its long-term safety and functionality. The South Carolina Department of Health and Environmental Control (SC DHEC) oversees the state regulation, permitting, inspection, and enforcement of Forty Niner Lake Dam, demonstrating a commitment to preserving water resources and safeguarding the surrounding community. With William R. Timmons IV representing the area in Congress, there is a strong emphasis on environmental conservation and responsible water management, highlighting the importance of sustainable practices in maintaining this vital infrastructure.
As water resource management becomes increasingly crucial in the face of climate change, Forty Niner Lake Dam serves as a valuable asset in providing recreational opportunities while also serving as a reminder of the ongoing need for proactive maintenance and risk management. With a moderate risk assessment rating and a history dating back to the mid-20th century, this earth dam on the TR-MEADOW FORK stream stands as a testament to the intersection of human ingenuity and environmental responsibility, inviting visitors to appreciate the beauty of nature while also recognizing the importance of preserving and protecting our water resources for future generations.
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 Forty Niner Lake Dam
Where does the data for Forty Niner 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 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.
