About this dam

Put08

Put08 is a private recreational dam located in East Palatka, Florida, along a St. Johns River tributary. Managed by the SJRWMD, this earth dam stands at 6 feet high with a hydraulic height of 4 feet and a length of 7400 feet. The dam provides a storage capacity of 123 acre-feet, with a normal storage of 64 acre-feet and a surface area of 25 acres. Despite its fair condition assessment in 2017, the dam poses a significant hazard potential and is classified as having a moderate risk level.

Owned by a private entity, Put08 serves primarily for recreational purposes and is regulated by the state of Florida. The dam lacks an emergency action plan and has not been modified in recent years. With an uncontrolled spillway type and a hazard potential rating of 'Significant', Put08 requires careful monitoring and maintenance to ensure the safety of the surrounding community and the integrity of the structure. The dam's location in Putnam County highlights its importance in managing water resources and mitigating potential climate-related risks in the region.

With a close proximity to the Jacksonville District, Put08 is subject to regular state inspections and enforcement, indicating a commitment to ensuring its functionality and safety. The dam's design, constructed primarily with stone and rock foundations, reflects a balance between structural integrity and environmental considerations. As water resource and climate enthusiasts, understanding the significance of dams like Put08 in managing water flow, storage, and recreation is crucial for sustainable development and resilience 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.

FAQ

About Put08

Where does the data for Put08 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.
