Summary

8 Dam, located in Pine Grove, Ohio, is a local government-owned structure designed by USDA NRCS with a primary purpose of flood risk reduction. Completed in 1972, this earth dam stands at a height of 36.4 feet and stretches 500 feet in length. With a storage capacity of 613.1 acre-feet and a drainage area of 2.03 square miles, the dam serves as a critical flood control measure for the tributary to Sperry Fork.

The dam's hazard potential is deemed significant, with a fair condition assessment as of November 2020. Its spillway type is uncontrolled, and it has uncontrolled outlet gates. Despite its moderate risk assessment, the dam has a solid track record and is inspected every five years. With the Department of Natural Resources as the state regulatory agency overseeing its operations, Pine Creek Structure No. 8 Dam plays a vital role in safeguarding the surrounding area from potential flood events. For water resource and climate enthusiasts, this dam is a fascinating example of engineering ingenuity and environmental stewardship in action.

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.
