Summary
2 Dam, located in Alledonia, Ohio, serves as a vital water supply source for the region. Built in 1936 by THE JENNINGS-LAWRENCE CO., COLUMBUS, OHIO, this earth dam stands at 48.3 feet high and spans 430 feet in length. It has a storage capacity of 228 acre-feet, with a normal storage level of 179 acre-feet, covering a surface area of 12.8 acres. The dam is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite its critical role in water supply management, the Barnesville Reservoir No. 2 Dam is classified as having a high hazard potential and a poor condition assessment. The dam's last inspection in October 2017 highlighted the need for improvements to enhance its structural integrity and reduce risks associated with its operation. The emergency action plan for the dam was last revised in June 2020, indicating ongoing efforts to address potential safety concerns and mitigate any potential hazards.
As water resource and climate enthusiasts, it is important to closely monitor the maintenance and risk management measures for dams like Barnesville Reservoir No. 2. By staying informed about the condition of such critical infrastructure, stakeholders can advocate for necessary investments in dam safety and resilience to ensure the long-term sustainability of water resources in the region. The collaboration between local government, regulatory agencies, and the community is essential to safeguarding water supply systems and adapting to the challenges posed by climate change.

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.
