Johnson Lake Dam dam
Johnson Lake Dam
Johnson Lake Dam, located in East Cambridge, Ohio, serves as a vital recreational resource for the community. Completed in 1976, this earth dam stands at a height of 12.4 feet and has a storage capacity of 55 acre-feet. The dam's primary purpose is for recreation, providing a serene setting for activities such as fishing, boating, and wildlife observation on its 10-acre surface area.
Managed by a private owner, Johnson Lake Dam is regulated by the Department of Natural Resources in Ohio, ensuring its compliance with state permitting, inspection, and enforcement requirements. With a low hazard potential and fair condition assessment as of October 2017, the dam continues to provide a safe and enjoyable environment for visitors. The dam's location near Leatherwood Creek offers a picturesque backdrop for water resource and climate enthusiasts seeking a tranquil escape in Guernsey County.
Overall, Johnson Lake Dam stands as a testament to responsible water resource management and offers a valuable recreational outlet for the local community. Its role in providing a sustainable water source for leisure activities underscores the importance of maintaining and safeguarding our natural resources for future generations to enjoy. With its scenic surroundings and well-maintained infrastructure, Johnson Lake Dam is a must-visit destination for those interested in both water conservation and outdoor recreation.

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.
- 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.
- 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.
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, environmental 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.

About Johnson Lake Dam
Where does the data for Johnson Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
