Summary
Standing at a height of 30 feet, this earth dam with a buttress core type serves as a popular spot for outdoor enthusiasts seeking water-based activities in Marion County. The dam boasts a storage capacity of 96 acre-feet, providing ample opportunity for boating, fishing, and wildlife observation on its 6-acre surface area.
Despite its recreational allure, Frankenbach Bros Lake Dam also poses a high hazard potential, emphasizing the need for vigilant maintenance and oversight. With a condition assessment currently listed as "Not Rated," there is a call for regular inspections and potential risk management measures to ensure the safety of visitors and the surrounding community. While the dam's emergency action plan status and risk assessment details remain unclear, the dam's proximity to TR-SOUTH RIVER and its designation as a high-risk structure underscore the importance of proactive monitoring and preparedness in the face of potential emergencies.
As water resource and climate enthusiasts seek to engage with the natural beauty and recreational opportunities offered by Frankenbach Bros Lake Dam, a deeper understanding of its structural integrity, hazard potential, and emergency preparedness is essential. With its private ownership and significant storage capacity, this earth dam serves as both a haven for outdoor enjoyment and a potential focal point for ongoing risk management efforts in the region.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
