Summary
With a height of 26.3 feet and a length of 400 feet, the dam holds a maximum storage capacity of 59 acre-feet and covers a surface area of 5.2 acres. The dam is situated on a tributary to Orrville Ditch in Wayne County, Ohio, and is regulated by the Department of Natural Resources.
Despite its low hazard potential, Stoll Lake Dam is currently in poor condition according to its last inspection in July 2020. The dam has a drainage area of 0.45 square miles and a normal storage capacity of 28.8 acre-feet. While the dam's primary purpose is for recreation, its structural integrity and maintenance need to be closely monitored to ensure the safety of the surrounding area and water resources.
Enthusiasts of water resources and climate change should take note of Stoll Lake Dam as a significant structure in Ohio, highlighting the importance of proper dam management and inspection protocols. With its historical significance and recreational value, the dam serves as a reminder of the delicate balance between human activities and environmental conservation in our changing climate.

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.
