Structure 68 dam
Structure 68
Structure 68, located in Highlands County, Florida, is a state-regulated dam on Canal C-41 with a primary purpose of flood risk reduction. This earth dam stands at 13 feet tall, with a hydraulic height of 9 feet and a dam height of 11 feet. It has a storage capacity of 2200 acre-feet and covers a surface area of 216 acres. Despite its significant hazard potential, the dam is currently in satisfactory condition, as assessed in September 2014.
Owned by the State of Florida, Structure 68 serves not only flood risk reduction but also irrigation purposes. Its uncontrolled outlet gates allow for water flow management, contributing to the overall water resource management in the region. With its location in Lake Placid and association with the Jacksonville District of the US Army Corps of Engineers, Structure 68 plays a crucial role in mitigating flood risks and ensuring water security for the surrounding communities.
Although last inspected in September 2014, Structure 68 remains an essential infrastructure for water resource and climate enthusiasts to monitor. Its role in flood risk reduction and irrigation, coupled with its state-regulated status and satisfactory condition, highlight the importance of ongoing maintenance and inspection to safeguard both the dam's integrity and the communities it serves. As water resource management and climate adaptation become increasingly vital, structures like Structure 68 play a crucial role in ensuring the resilience of water systems in the face of changing environmental conditions.

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 Structure 68
Where does the data for Structure 68 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.
