Summary

Completed in 2007, this earth dam stands at a height of 12 feet with a hydraulic height of 9 feet, providing a maximum storage capacity of 12,899 acre-feet. The primary purpose of this structure is for recreation, offering a surface area of 36 acres for activities such as boating and fishing.

This dam on the tributary of the Ocklawaha River is regulated by the St. Johns River Water Management District, ensuring state permitting, inspection, and enforcement. With a controlled spillway and slide gates for outlet control, Sjrwmd Structure E-2 has a hazard potential rated as high, but its condition assessment as fair. Despite its very high risk assessment, measures for risk management and emergency preparedness are not explicitly detailed in the available data.

Overall, Sjrwmd Structure E-2 serves as a vital resource for water management and recreational activities in the area, highlighting the importance of maintaining its structural integrity and implementing effective risk management strategies to ensure the safety of surrounding communities and the preservation of the local ecosystem.

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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.

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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
