Summary

Built in 1960 by the USDA Soil Conservation Service, this earth-type dam stands at a height of 22.3 feet and spans 500 feet in length. With a storage capacity of 79 acre-feet, the dam sits on a tributary to Caesar Creek, serving as a vital resource for water management in the area.

Despite its recreational purpose, Fisher Lake Dam poses a significant hazard potential with a poor condition assessment as of the last inspection in March 2019. The dam's maintenance and safety measures are regulated by the Ohio Department of Natural Resources, with state permitting, inspection, and enforcement in place. The dam's drainage area is 0.55 square miles, with a maximum discharge capacity of 958 cubic feet per second, highlighting the importance of proper management and maintenance to ensure public safety and environmental protection.

As water resource and climate enthusiasts, it is crucial to monitor and advocate for the proper management of Fisher Lake Dam to mitigate potential risks and ensure its long-term sustainability. With the dam's significant hazard potential and poor condition assessment, efforts must be made to improve maintenance practices, conduct regular inspections, and implement necessary safety measures to protect the surrounding community and ecosystem. Collaboration between private owners, regulatory agencies, and local stakeholders is essential to safeguard this important water resource for future generations.

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.
