Summary
21, located in Cherry Valley, Ohio, is a privately owned earthen dam that serves primarily for recreational purposes. Standing at a height of 41 feet and stretching 945 feet in length, this dam has a storage capacity of 114 acre-feet and covers a surface area of 7.6 acres. It is situated on a tributary to Piney Fork, within the jurisdiction of the Department of Natural Resources in Ohio, ensuring state regulation, permitting, inspection, and enforcement are in place.
Despite its significant hazard potential, Jeffco Pond Dam No. 21 has been assessed as being in poor condition as of November 2017. The dam's Emergency Action Plan (EAP) was last revised in June 2013, raising concerns about its current adherence to safety guidelines. With an inspection frequency of 5 years, it is crucial for stakeholders to prioritize necessary risk management measures and ensure the dam's structural integrity to mitigate potential hazards and protect the surrounding community.
For water resource and climate enthusiasts, Jeffco Pond Dam No. 21 serves as a focal point for understanding the complexities of managing recreational dams in Ohio. With its location in a critical watershed area and the potential risks associated with its condition, this dam underscores the importance of proactive maintenance, emergency preparedness, and regulatory oversight to safeguard water resources and ensure public safety in the face of changing climatic conditions.

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.
