Summary

Built in 1963 by the USDA NRCS, this dam serves the primary purpose of recreation, offering a surface area of 3.5 acres for outdoor enthusiasts to enjoy. The dam stands at a height of 28.6 feet and has a storage capacity of 46.5 acre-feet, with a normal storage level of 21.4 acre-feet.

This dam is regulated by the Department of Natural Resources in Ohio and undergoes regular inspections, with the last assessment conducted in March 2016. Despite being classified as having a high hazard potential, the dam is currently rated as being in fair condition. The spillway is uncontrolled, with a maximum discharge capacity of 189 cubic feet per second. The risk assessment for the dam is moderate, indicating a level 3 risk, and no Emergency Action Plan (EAP) has been prepared as of the latest available data in May 2021.

Charylie's Lake Dam provides a picturesque recreational spot in the heart of Ohio, offering a tranquil escape for visitors seeking outdoor activities such as fishing, boating, and hiking. With its historical significance dating back to the 1960s, this dam continues to be a vital part of the local landscape, contributing to the beauty and allure of the surrounding area while also serving as a reminder of the importance of proper dam management and safety protocols in the face of potential risks and hazards.

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.
