Mem1 dam
Mem1
Mem1 is a private dam located in Hamilton County, Florida, specifically in the city of Jasper. The dam, designed for recreation purposes, stands at a height of 12 feet and stretches over a length of 5091 feet, creating a surface area of 131 acres. Situated on an unnamed pond, Mem1 is regulated by the Florida Department of Environmental Protection (FDEP) and adheres to state permitting, inspection, and enforcement protocols.
With a storage capacity of 2394 acre-feet, Mem1 poses an undetermined hazard potential and currently holds a condition assessment of "Not Rated." The dam's emergency action plan status, risk assessment, and management measures remain unaddressed, highlighting potential areas for improvement in emergency preparedness. Despite lacking specific details on modification history, inspection frequency, and contact information, Mem1's significance lies in its role as a recreational structure within the Jacksonville District of Florida.
For water resource and climate enthusiasts, Mem1 presents an intriguing case study of a privately owned dam in a state-regulated environment. The dam's location, purpose, and design offer valuable insights into the intersection of human activity with natural water systems. As efforts continue to assess and manage potential risks associated with dams like Mem1, the importance of proactive monitoring and emergency planning becomes increasingly apparent in safeguarding water resources and communities from potential hazards.

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 Mem1
Where does the data for Mem1 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.
