Grogg Lake Dam dam
Grogg Lake Dam
Grogg Lake Dam, located in Richland County, Ohio, is a privately-owned earth dam completed in 2001 with a primary purpose of recreation. The dam stands at a height of 17.3 feet and has a storage capacity of 65.3 acre-feet, providing a surface area of 11.1 acres for recreational activities. Situated on a tributary to the Mohican River, the dam is regulated by the Ohio Department of Natural Resources and undergoes regular inspections to ensure its safety and structural integrity.
With a low hazard potential and a satisfactory condition assessment as of October 2019, Grogg Lake Dam serves as a vital resource for the Greer community and surrounding areas. The dam's design and construction were overseen by J&L Engineering, and it is subject to state jurisdiction, permitting, and enforcement. Despite its remote location, the dam offers a picturesque setting for outdoor enthusiasts and nature lovers to enjoy various recreational activities such as boating, fishing, and bird-watching.
As a key feature in the local landscape, Grogg Lake Dam plays a crucial role in water resource management and climate resilience efforts in the region. Its importance lies not only in providing recreational opportunities but also in contributing to the overall ecosystem health of the area. With its strategic location and regulated operations, the dam serves as a model for sustainable water management practices and underscores the significance of preserving and protecting our natural resources for future generations.

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.
Plan around the weather
Same NOAA / yr.no feed Snoflo's iOS app uses. Watch the precipitation column on the meteogram -- rain on the basin upstream typically lifts inflow 24-72 hours later.

About Grogg Lake Dam
Where does the data for Grogg 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.
