Summary

Completed in 1968, this earth dam stands at a height of 44.7 feet and has a reservoir with a storage capacity of 76.4 acre-feet. The dam's condition is assessed as fair, with a significant hazard potential and a moderate risk rating.

Managed by the Department of Natural Resources in Ohio, Stoneybrook Farm Lake Dam is regularly inspected and permitted by the state regulatory agency. The dam, which is a tributary to Newman Run, has an uncontrolled spillway and outlet gates. Despite its fair condition, the dam poses a significant risk, prompting the need for continued monitoring and potential risk management measures to ensure the safety of the surrounding community and environment.

For water resource and climate enthusiasts, Stoneybrook Farm Lake Dam serves as a fascinating case study in dam infrastructure, highlighting the intersection of recreation, water management, and regulatory oversight. With its historical significance and ongoing maintenance needs, this dam offers valuable insights into the challenges and opportunities associated with managing water resources in an environmentally conscious and sustainable manner.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
