Upper Supply Dam dam
Upper Supply Dam
Upper Supply Dam in Cadiz, Ohio, is a privately-owned earth dam primarily used for water supply purposes. The dam stands at a height of 10 feet and spans a length of 500 feet, with a storage capacity of 198 acre-feet. Located in Harrison County, Ohio, the dam is under the jurisdiction of the Mine Safety and Health Administration for regulatory oversight and inspections. With a low hazard potential, the dam's condition assessment is currently not available.
Despite being a non-federally regulated structure, Upper Supply Dam plays a crucial role in providing water supply to the surrounding area. While details about the dam's construction year and specific design features are not provided, its importance in water resource management cannot be understated. The dam's location, just 2 miles from Cadiz, makes it a key infrastructure component for ensuring a reliable water source for the community.
Although lacking in detailed information about its maintenance and emergency preparedness measures, Upper Supply Dam serves as a vital resource for water supply in the region. As climate change continues to impact water resources, the proper management and maintenance of such infrastructure will be essential in ensuring water security for the future. Additionally, with its low hazard potential, the dam presents a relatively stable and reliable source of water supply for the local area.

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 Upper Supply Dam
Where does the data for Upper Supply 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 Low 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.
