Summary

Stilson & Associates in 1949 for offstream water storage. With an earth dam type standing at 18 feet high and stretching 820 feet in length, the reservoir has a storage capacity of 33.7 million gallons, serving as a critical water resource for the community. Despite its significant hazard potential and unsatisfactory condition assessment, the Department of Natural Resources in Ohio regulates and inspects the dam regularly to ensure public safety.

This reservoir plays a crucial role in managing water supply and mitigating climate-related risks in the region. It covers a surface area of 1.9 acres and drains a small watershed area of 0.02 square miles, providing essential water storage for local needs. The dam's location in Clarksville, Ohio, highlights its strategic importance in safeguarding the community against potential flooding and ensuring a stable water supply throughout the year. With a close distance to the city, the reservoir serves as a key infrastructure asset for water resource management.

As climate change intensifies, the maintenance and regulation of dams like Clarksville Upground Reservoir become increasingly vital. With state oversight from the Department of Natural Resources and regular inspections, the dam continues to provide essential water storage while addressing safety concerns. Its role in water management and climate resilience underscores the importance of sustainable infrastructure investments to protect communities and ecosystems in the face of changing environmental conditions.

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.
