Ajl1 dam
Ajl1
Ajl1 is a private dam located in Hamilton County, Florida, specifically in the city of Jasper. This earth-type dam, standing at a height of 10 feet with a length of 2478 feet, serves primarily for recreational purposes, offering a surface area of 57 acres and a storage capacity of 915 acre-feet. Situated on an unnamed pond in the Jacksonville District, this dam is regulated by the Florida Department of Environmental Protection (FDEP), with state permitting, inspection, and enforcement in place to ensure its safety and compliance.
Despite being categorized as having an undetermined hazard potential and not currently rated for condition assessment, Ajl1 remains an intriguing water resource structure for enthusiasts interested in the intersection of dams, climate, and environmental management. With its location in a picturesque setting and its recreational focus, this dam presents an opportunity to explore the dynamics of water storage, habitat preservation, and the regulatory framework that governs such structures. As climate change continues to impact water resources, understanding the role of dams like Ajl1 becomes increasingly crucial for sustainable water management in the face of shifting environmental conditions.
While Ajl1 may not have a detailed risk assessment or emergency action plan in place, its presence as a private dam in Florida highlights the diverse landscape of water infrastructure across the state. As climate enthusiasts delve into the complexities of water resource management, Ajl1 serves as a case study for the balancing act between human recreation, ecological considerations, and regulatory oversight in the realm of dams and reservoirs. This data-rich profile invites further exploration and analysis for those passionate about water resources, climate resilience, and the intricate dynamics of human-made structures in natural landscapes.
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 Ajl1
Where does the data for Ajl1 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 Undetermined 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.
