Summary
Completed in 1981, this earth dam stands at a height of 35 feet and has a length of 320 feet, creating a reservoir with a storage capacity of 22.8 acre-feet. The dam regulates a tributary to Clear Fork Creek and is under the regulatory authority of the Department of Natural Resources in Ohio.
With a low hazard potential and fair condition assessment as of the last inspection in September 2017, Larrick Lake Dam is deemed to be in satisfactory operational state. The dam's emergency action plan status and risk management measures are not explicitly specified in the available data, but its maintenance and regulatory oversight by state agencies ensure that it meets safety standards. The dam provides recreational opportunities and environmental benefits, serving as a vital water resource for the local community and contributing to the overall ecosystem health in the region.
As a significant feature in the water resource management of Guernsey County, Ohio, Larrick Lake Dam plays a crucial role in providing water storage, flood control, and recreational opportunities for residents and visitors alike. Its construction and operation reflect a commitment to sustainable water management practices, with state agencies overseeing its regulation, inspection, and enforcement. As climate change impacts water resources, the resilience and effectiveness of structures like Larrick Lake Dam become increasingly important in ensuring the continued availability and quality of water for both human and environmental needs.

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.
