About this dam

Shelby Upground Reservoir No. 2

Shelby Upground Reservoir No. 2, located in Richland County, Ohio, is a vital water supply source managed by the local government. Constructed in 1955 by DESIGN ASSOCIATES, this Earth-type dam stands at a height of 48 feet with a length of 4840 feet, providing a storage capacity of 789 acre-feet. The reservoir covers an area of 28.2 acres and is fed by offstream flow from the Black Fork Mohican River.

This reservoir plays a crucial role in water resource management for the city of SHELBY, serving as a primary source of water supply. It is regulated and inspected by the Ohio Department of Natural Resources, ensuring its safety and compliance with state regulations. With a high hazard potential but a satisfactory condition assessment, the dam is monitored and maintained to mitigate any potential risks and ensure the safety of the surrounding community.

Water resource and climate enthusiasts will appreciate the significance of Shelby Upground Reservoir No. 2 in securing water supply for the region while also recognizing the importance of proper maintenance and regulation to prevent any potential hazards. The reservoir stands as a testament to the careful balance between water resource management and environmental stewardship, highlighting the critical role of infrastructure in sustaining communities 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.

FAQ

About Shelby Upground Reservoir No. 2

Where does the data for Shelby Upground Reservoir No. 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.
