Lake Larc Dam dam
Lake Larc Dam
Lake Larc Dam, nestled in the heart of Lake Asbury, Florida, stands as a private water resource gem that caters primarily to recreational enthusiasts. With a structural height of 19 feet and a hydraulic height of 12 feet, this earth-type dam boasts a storage capacity of 3000 acre-feet, offering a serene surface area of 6 acres for visitors to enjoy. Despite its fair condition assessment as of September 2020, the dam poses a high hazard potential, emphasizing the importance of regular inspections and maintenance to ensure public safety.
Owned by a private entity, Lake Larc Dam is regulated by the state of Florida, with permitting, inspection, and enforcement measures in place to uphold its integrity. Situated within Clay County, the dam's purpose is solely focused on recreation, providing a tranquil escape for locals and tourists alike. Its proximity to the bustling city of Lake Asbury makes it a popular destination for outdoor enthusiasts seeking a serene environment to unwind and connect with nature.
With designated emergency action plans in place, Lake Larc Dam continues to be a vital component of the local water resource infrastructure. Despite its age and the inherent risks associated with its high hazard potential, the dam remains a beloved landmark in the region, offering a picturesque setting for water and climate enthusiasts to explore and appreciate the beauty of this man-made marvel.
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.
Plan around the weather

About Lake Larc Dam
Where does the data for Lake Larc 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.
