About this dam

Spring Lake

Spring Lake, located in Satsuma, Florida, is a privately owned water resource with a primary purpose of fire protection, stock, and small fish pond. The dam, primarily made of earth with stone core types and rock and soil foundations, stands at a height of 12 feet with a hydraulic height of 9 feet. The reservoir has a storage capacity of 84 acre-feet and covers an area of 17 acres, serving as a recreational spot for enthusiasts.

Despite its significance as a water source, Spring Lake has been assessed to be in poor condition with a significant hazard potential. The last inspection in May 2016 revealed the need for improvement to meet safety standards. The dam features an uncontrolled spillway with a width of 5 feet and lacks outlet gates. The risk assessment indicates a moderate risk level, prompting the need for enhanced risk management measures to ensure the safety and integrity of the structure.

Although Spring Lake is not under the jurisdiction of any federal agency, it is subject to regulation and inspection by the state. With its close proximity to the Deep Creek Tributary, the reservoir plays a crucial role in providing water for fire protection and recreational activities. As water resource and climate enthusiasts, efforts must be made to address the poor condition of Spring Lake to mitigate risks and ensure sustainable management for future generations to enjoy.

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.

FAQ

About Spring Lake

Where does the data for Spring Lake 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.
