Summary
With a structural height of 83 feet and a hydraulic height of 56 feet, the dam has a storage capacity of 203,000 acre-feet and a dam volume of 155,500 cubic yards. The dam features an uncontrolled spillway with a width of 338 feet and 18 slide (sluice) gates for water release.
Managed and funded by the US Army Corps of Engineers, Dover Dam is equipped with risk management measures to address potential flooding hazards. Regular inspections, maintenance, and repairs ensure the dam's structural integrity, while an emergency action plan is in place to coordinate responses in case of a dam-related emergency. The dam's risk assessment is rated as moderate, with ongoing efforts to monitor water levels and engage with local emergency managers and the public to raise awareness and support preparedness.
Dover Dam serves as a critical infrastructure in managing water flow along the Tuscarawas River, highlighting the importance of maintaining and monitoring dams to mitigate flood risks. As climate change continues to impact weather patterns, the need for effective dam management and risk assessment becomes increasingly crucial in safeguarding communities and ecosystems from potential flooding events.

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.
