Summary
Completed in 1968, this earth dam stands at a height of 44.6 feet and has a storage capacity of 137.1 acre-feet. With a primary purpose of recreation, the dam provides not only a picturesque lake but also opportunities for water-based activities in the surrounding area.
Despite being assessed as in fair condition during the last inspection in October 2018, Lake Legendary Dam is classified as having a significant hazard potential. The dam, with a length of 430 feet and a surface area of 6.5 acres, plays a crucial role in regulating the flow of the tributary to Blount Run and has a maximum discharge capacity of 171 cubic feet per second. The dam's emergency action plan was last revised in June 2020, indicating ongoing efforts to ensure the safety and integrity of the structure.
Enthusiasts of water resources and climate management will find Lake Legendary Dam to be an intriguing case study in the intersection of recreational use and dam safety. With its location in Muskingum County, Ohio, and under the jurisdiction of the state regulatory agency, this dam serves as a vital component in the local ecosystem while also posing potential risks that necessitate careful monitoring and maintenance. As the debate over water resource management and climate resilience continues, Lake Legendary Dam presents a compelling example of the complexities involved in balancing human recreation with environmental protection.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
