Summary

This offstream reservoir serves as a primary source for water supply purposes, with a storage capacity of 1,035 acre-feet and a surface area of 55.9 acres. Despite its crucial role, the reservoir's condition assessment is rated as poor, with a high hazard potential, indicating the need for maintenance and upgrades to ensure its continued functionality.

Managed by the local government and regulated by the Ohio Department of Natural Resources, Amicks Upground Reservoir is subject to state inspection, permitting, and enforcement. The reservoir stands at a dam height of 40 feet, stretching 4,500 feet in length. Its drainage area covers 0.09 square miles, highlighting its importance in the region's water management system. With a maximum discharge capacity of 45 cubic feet per second, the reservoir plays a significant role in water resource management in the area.

Despite its aging infrastructure and maintenance challenges, Amicks Upground Reservoir remains a critical water supply asset in Morrow County, Ohio. As climate change continues to impact water resources, ensuring the resilience and safety of such structures becomes increasingly important. With ongoing assessments and potential risk management measures, the reservoir can continue to serve its community effectively while adapting to the evolving climate 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.
