Summary

With a height of 28.8 feet and a length of 350 feet, this dam creates a reservoir with a storage capacity of 695 acre-feet and a surface area of 53.4 acres. The dam is situated on a tributary to the Grand River and is regulated by the Department of Natural Resources in Ohio.

Despite its significant hazard potential, Lake Asegra Dam is currently in poor condition, as assessed in May 2016. The dam has a history of inspections with a frequency of every 5 years, with the last inspection conducted in 2016. The Emergency Action Plan (EAP) was last revised in June 2017, indicating a commitment to ensuring the safety and security of the surrounding community in case of any emergencies related to the dam.

Water resource and climate enthusiasts visiting Lake Asegra Dam can appreciate its recreational value while also being aware of the need for ongoing maintenance and monitoring to ensure its safety. The dam's location in Ashtabula County, Ohio, offers a picturesque setting for outdoor activities, but its condition assessment and hazard potential highlight the importance of responsible management and oversight to prevent any potential risks to the surrounding area.

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.
