Forest Lake Dam dam
Forest Lake Dam
Forest Lake Dam, located in Florence, South Carolina, serves as a vital structure for debris control, irrigation, and recreation purposes along the Middle Swamp river. Built in 1962, this private Earth dam stands 16 feet tall and stretches 445 feet in length, with a storage capacity of 1,617 acre-feet. Despite its fair condition assessment and significant hazard potential, the dam is regularly inspected by the South Carolina Department of Health and Environmental Control to ensure public safety.
The dam's primary purpose of debris control is crucial for maintaining water quality and preventing blockages in the surrounding area. With a normal storage capacity of 677 acre-feet and a surface area of 172 acres, Forest Lake Dam plays a key role in managing water resources in the region. The dam's condition is closely monitored, and emergency action plans are in place to address any potential risks or hazards that may arise.
Owned and regulated by private entities, Forest Lake Dam is an essential component of the local water infrastructure, providing valuable services to the community while also offering recreational opportunities for residents and visitors. As climate change continues to impact water resources and weather patterns, the maintenance and upkeep of dams like Forest Lake Dam are critical to ensuring the resilience and sustainability of water systems in the face of evolving environmental challenges.

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 Forest Lake Dam
Where does the data for Forest 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 Significant 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.
