Arnett Lake No. 2 Dam dam
Arnett Lake No. 2 Dam
Arnett Lake No. 2 Dam, located in Warren County, Ohio, is a privately owned earth dam primarily used for recreation purposes. Constructed in 1967 by the USDA Soil Conservation Service, this dam stands at a height of 13.3 feet and has a length of 390 feet. With a storage capacity of 30 acre-feet, the dam serves as a vital water resource for the surrounding area, providing normal storage of 12.9 acre-feet and covering a surface area of 4.1 acres.
State regulated and inspected by the Department of Natural Resources, Arnett Lake No. 2 Dam has been assessed to be in fair condition with a significant hazard potential. The last inspection conducted in July 2019 revealed that the dam meets safety guidelines, although there are some areas that may require attention to ensure continued structural integrity. With a maximum discharge capacity of 680 cubic feet per second, the dam plays a crucial role in managing water flow in the tributary to North Fork River.
As a key feature in the local landscape, Arnett Lake No. 2 Dam not only provides recreational opportunities but also serves as an important infrastructure for water resource management in the region. With ongoing inspections and maintenance, the dam continues to play a vital role in safeguarding against potential risks and ensuring the safety of surrounding communities and ecosystems.

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 Arnett Lake No. 2 Dam
Where does the data for Arnett Lake No. 2 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 Significant 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.
