Summary
Designed by Edward F. Gasser from New Philadelphia, Ohio, this dam stands at a height of 30 feet and spans a length of 550 feet, creating a reservoir with a storage capacity of 29.8 acre-feet. Situated on a tributary to the Tuscarawas River, this dam offers a serene 2.5-acre surface area for outdoor enthusiasts to enjoy activities such as fishing, boating, and picnicking.
Managed by the Department of Natural Resources in Ohio, Lake Greenbriar Dam has a low hazard potential and has been assessed as satisfactory in condition as of July 2020. Regular inspections are conducted every five years to ensure the safety and integrity of the structure. The dam is equipped to handle a maximum discharge of 580 cubic feet per second, providing flood protection to the surrounding area. With its scenic location and well-maintained facilities, Lake Greenbriar Dam remains a popular destination for water resource and climate enthusiasts seeking a tranquil outdoor experience in the heart of Ohio.
Overall, Lake Greenbriar Dam serves as a vital recreational site in Tuscarawas County, offering a peaceful retreat for visitors to connect with nature and enjoy the beauty of the surrounding landscape. As a privately owned structure regulated by the state, this dam exemplifies the importance of responsible water resource management and underscores the need for ongoing monitoring and maintenance to ensure the safety of both the dam and the local community.

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.
