Willard City Upground Reservoir dam
Willard City Upground Reservoir
Located in Standarsburg, Ohio, the Willard City Upground Reservoir is a vital water supply resource managed by the local government. Constructed in 1971, this earth dam structure stands at a height of 64.5 feet, with a total storage capacity of 7,953 acre-feet. The reservoir serves as a primary source of water for the surrounding area, with a normal storage capacity of 6,134 acre-feet and a surface area of 212 acres.
Managed by the Department of Natural Resources in Ohio, the Willard City Upground Reservoir is regulated, permitted, inspected, and enforced by state authorities to ensure its safe operation. With a high hazard potential but a satisfactory condition assessment, the dam undergoes regular inspections every 5 years to maintain its structural integrity. The reservoir's location along the West Branch Huron River offstream provides essential water resources for the region, demonstrating its crucial role in water supply management.
Designed by JONES AND HENRY ENGINEERS, LTD. from Toledo, Ohio, the Willard City Upground Reservoir represents a significant infrastructure investment to meet the water supply needs of the local community. With its strategic location and ample storage capacity, this reservoir plays a pivotal role in water resource management and climate resilience efforts in Huron County, Ohio. As a key component of the region's water supply infrastructure, the Willard City Upground Reservoir serves as a critical asset in ensuring reliable access to clean water for the residents and industries it serves.
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 Willard City Upground Reservoir
Where does the data for Willard City Upground Reservoir 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.
