Dillon Dam - Nashport Dike dam
Dillon Dam - Nashport Dike
Dillon Dam - Nashport Dike, located in Zanesville, Ohio, is a federal structure managed by the US Army Corps of Engineers for the primary purpose of flood risk reduction along the Licking River. Completed in 1959, this earth dam stands at a height of 48 feet with a length of 1600 feet, providing a maximum storage capacity of 154,000 acre-feet.
With a high hazard potential, Dillon Dam is regularly monitored and maintained by the US Army Corps of Engineers to mitigate flood risks and ensure the structural integrity of the dam. Emergency action plans are in place, and risk management measures include continuous monitoring, prioritizing activities to reduce risks, and engaging with local emergency managers and the public to raise awareness and preparedness for potential dam-related emergencies.
Despite efforts to manage flood risks associated with the dam, the USACE acknowledges that dams do not eliminate all risk of flooding, especially during severe weather events. The agency works to address all types of flood risks, which may involve releasing water through the dam to regulate water levels or relieve pressure. Ongoing updates and improvements are made to enhance the dam's performance and resilience in the face of changing climate conditions.

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 Dillon Dam - Nashport Dike
Where does the data for Dillon Dam - Nashport Dike 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.
