Weymouth Valley Lake No. 1 Dam dam
Weymouth Valley Lake No. 1 Dam
Weymouth Valley Lake No. 1 Dam, located in Abbeyville, Ohio, is a significant earth dam completed in 1968 primarily for water supply purposes. Owned privately, this dam stands at a height of 12.2 meters with a length of 250 meters, creating a storage capacity of 19 acre-feet when filled to capacity. The dam is regulated and inspected by the Ohio Department of Natural Resources, ensuring its safety and compliance with state regulations.
Despite its essential role in water supply, the dam's condition assessment is rated as poor, with a significant hazard potential. The last inspection in October 2018 revealed this, prompting a closer monitoring and management approach to maintain its structural integrity and safety. With a drainage area of 0.09 square kilometers and a maximum discharge capacity of 2 cubic meters per second, the dam plays a crucial role in managing water resources in the region, contributing to the tributary of the West Branch Rocky River.
As water resource and climate enthusiasts, understanding the intricacies of dams like Weymouth Valley Lake No. 1 Dam provides insight into the vital infrastructure supporting water supply systems. With its location in Medina County, Ohio, and its role in water management, this dam serves as a reminder of the importance of maintaining and inspecting critical water infrastructure to ensure both safety and sustainability for the surrounding communities and ecosystems.
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 Weymouth Valley Lake No. 1 Dam
Where does the data for Weymouth Valley Lake No. 1 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.
