Summary
The dam has a height of 18.5 feet and a storage capacity of 49.5 acre-feet, with a surface area of 4.4 acres. It is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections to ensure its structural integrity. The dam is situated on a tributary to the Muskingum River, contributing to the overall water resource management in the region.
Constructed in 2000 by R.D. Zande for repairs, Carman Lake Dam has a significant hazard potential but is currently assessed to be in satisfactory condition as of the last inspection in November 2018. The dam has an emergency action plan in place, with the most recent revision made in June 2020. It is important for water resource and climate enthusiasts to monitor the maintenance and management of Carman Lake Dam to ensure the safety of the surrounding community and uphold its recreational value. The dam plays a crucial role in the local ecosystem and water flow dynamics, making it a key asset in the region's water resource infrastructure.

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.
