Summary

Built in 1980 by the USDA NRCS, this earth dam stands at a height of 55.3 feet and spans 2600 feet in length. With a storage capacity of 1519 acre-feet and a drainage area of 5.77 square miles, this structure plays a crucial role in managing water levels in the area.

Regulated by the Department of Natural Resources in Ohio, Chippewa Creek Structure III-A has a high hazard potential but is currently rated as being in satisfactory condition. Despite its uncontrolled spillway and outlet gates, the dam has been deemed to meet guidelines for emergency action plans. With a maximum discharge capacity of 32,397 cubic feet per second, this dam serves as a vital resource for flood control in the Medina County area, providing protection to surrounding communities.

Water resource and climate enthusiasts will appreciate the strategic design and operational oversight of Chippewa Creek Structure III-A. Its location on Hubbard Creek, its stone core and soil foundation, and its moderate risk assessment all contribute to its importance in mitigating flood risks and safeguarding the local environment. With regular inspections and a comprehensive emergency action plan in place, this dam exemplifies how infrastructure can effectively balance flood control needs with environmental stewardship in Ohio's water management efforts.

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.
