Summary
Built in 1964, this earth dam stands at a height of 28.9 feet and has a maximum storage capacity of 38.5 acre-feet. With a primary purpose of water supply, Mader Pond Dam plays a crucial role in providing water for various uses in the region, ensuring a reliable water source for residents and industries.
Despite its importance, Mader Pond Dam has been assessed as being in poor condition, with a low hazard potential. The dam is regulated by the Ohio Department of Natural Resources, and undergoes regular inspections to ensure its structural integrity and safety. The last inspection was conducted in May 2019, with a recommended inspection frequency of every 5 years to monitor its condition and mitigate any potential risks.
As water resources and climate enthusiasts, it is essential to recognize the significance of dams like Mader Pond Dam in securing water supply and managing water resources effectively. Continued monitoring, maintenance, and potentially rehabilitation efforts are crucial to ensure the long-term functionality and safety of this important infrastructure, especially in the face of changing climate conditions and increasing water demands.

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.
