Summary
1 Dam in Dresden, Ohio, stands as a significant structure designed by the Peabody Coal Company in 1962 for the purpose of tailings storage. This earth dam, with a height of 49 feet and a length of 705 feet, holds a storage capacity of 124 acre-feet and covers a surface area of 6.6 acres. Situated in Coshocton County and regulating a tributary to Mill Fork, this state-regulated dam is under the oversight of the Ohio Department of Natural Resources, ensuring regular inspections and enforcement to maintain safety standards.
Despite its historical significance and purpose, the Broken Aro Slurry Pond No. 1 Dam is currently assessed as being in poor condition with a significant hazard potential. The last inspection in 2018 revealed the need for improvements to meet safety guidelines and reduce risks associated with the dam. With a designated inspection frequency of 5 years, there is an urgent need for remedial action and risk management measures to enhance the dam's resilience and protect downstream areas in the event of a potential failure. Enthusiasts of water resources and climate science should closely monitor the ongoing maintenance and potential upgrades to this critical infrastructure to ensure the safety and sustainability of the surrounding environment.

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.
