Charles Mill Dam - Dike 2 dam
Charles Mill Dam - Dike 2
Charles Mill Dam - Dike 2, located in Mifflin, Ohio, is a Federal-owned earth dam constructed in 1936 by the US Army Corps of Engineers on the Black Fork of Mohican River. This dam stands at a hydraulic height of 8 feet and a structural height of 22 feet, with a length of 325 feet and a storage capacity of 43,000 acre-feet. While the dam does not have a spillway, it is equipped to manage water levels and maintain structural integrity through controlled releases.
With a high hazard potential and risk assessment rating of 2, the US Army Corps of Engineers actively manages flood risks associated with Charles Mill Dam. This includes regular monitoring, prioritizing maintenance activities, and engaging with emergency managers and the public to raise awareness and prepare for dam-related emergencies. The Corps also collaborates with local authorities to update emergency action plans and ensure the dam's proper functioning through maintenance and repairs.
Despite the inherent risks of flooding and water management, the US Army Corps of Engineers continues to work diligently to mitigate potential issues at Charles Mill Dam - Dike 2. By prioritizing safety, proactive monitoring, and community engagement, the Corps aims to ensure the dam's resilience and effectiveness in protecting the surrounding area from flood events.

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 Charles Mill Dam - Dike 2
Where does the data for Charles Mill Dam - Dike 2 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 High 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.
