Summary

2 is a vital water supply infrastructure located in Preble, Ohio, designed by the Ralph L. Woolpert Co. in 1965. This Earth-type dam stands at a height of 13.5 feet and has a storage capacity of 57.5 acre-feet, serving the purpose of water supply for the local community of Talawand Springs. The dam is regulated by the Department of Natural Resources in Ohio, ensuring that it meets state inspection and enforcement standards.

Despite its importance for water resource management, College Corner Upground Reservoir No. 2 is currently assessed as being in poor condition with a significant hazard potential. The last inspection in April 2016 highlighted the need for maintenance and potential risk management measures. The dam's emergency action plan status and risk assessment are currently unknown, underscoring the importance of ongoing monitoring and maintenance to ensure the safety and reliability of this critical water infrastructure.

As water resource and climate enthusiasts, it is crucial to stay informed about the state of College Corner Upground Reservoir No. 2 and advocate for necessary upgrades and maintenance to mitigate potential risks and ensure the sustainable management of water resources in the region. By understanding the vital role of infrastructure like this dam in providing clean water to communities, we can work towards preserving and enhancing these essential systems for future generations.

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.
