East Reservoir Dam dam
East Reservoir Dam
East Reservoir Dam, located in Portage Lakes, Ohio, is a state-regulated structure owned by the State of Ohio. It was completed in 1840 and serves the primary purpose of recreation, with a normal storage capacity of 6,896 acre-feet and a maximum storage of 8,796 acre-feet. The dam, standing at a height of 24.8 feet, impounds water from a tributary to the Tuscarawas River, creating a surface area of 900 acres for recreational activities.
The dam has a high hazard potential but was rated as satisfactory in its last condition assessment in 2015. The Department of Natural Resources oversees the regulation, permitting, inspection, and enforcement of the dam. The structure spans 1,300 feet in length and has a drainage area of 13.2 square miles. Despite its age, East Reservoir Dam has been maintained to meet safety standards and has an emergency action plan in place, with regular inspections every five years to ensure its integrity.
East Reservoir Dam not only provides recreational opportunities for the community but also plays a crucial role in water resource management in the region. With its historic significance and ongoing maintenance efforts, the dam serves as a vital infrastructure for both flood control and water supply, highlighting the intersection of water resources and climate resilience in the area.
Dam data reference
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 East Reservoir Dam
Where does the data for East Reservoir 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 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.
