No. 1-West Of Cornwallis dam
No. 1-West Of Cornwallis
No. 1-West of Cornwallis is a historic earth dam located in Ritchie County, West Virginia, near the city of Cairo. Completed in 1863, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. The dam has a height of 31 feet and a storage capacity of 41 acre-feet, with a normal storage level of 23 acre-feet.
Situated on the Hughes River, No. 1-West of Cornwallis is regulated by the West Virginia Department of Environmental Protection and undergoes regular state inspections for safety and compliance. Despite its age, the dam has a low hazard potential and has not been formally assessed for its current condition. While it does not have a designated Emergency Action Plan (EAP) or inundation maps prepared, the dam remains an integral part of the local water resource infrastructure.
With its rich history and continued functionality, No. 1-West of Cornwallis is a testament to the enduring importance of water resource management in the region. As a private-owned structure, this dam plays a crucial role in supporting local fire protection efforts and providing essential water resources for livestock and recreational purposes. As climate change continues to impact water resources, the preservation and maintenance of structures like No. 1-West of Cornwallis will be vital in ensuring the continued sustainability of the surrounding communities and ecosystems.

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 No. 1-West Of Cornwallis
Where does the data for No. 1-West Of Cornwallis 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.
