Harmon Creek No. 2 Dam dam
Harmon Creek No. 2 Dam
Harmon Creek No. 2 Dam, located in Weirton, West Virginia, is a vital structure for flood risk reduction along Crail Run. Built in 1973 by the USDA NRCS, this earth dam stands at a height of 71 feet, with a hydraulic height of 70 feet and a length of 340 feet. It has a storage capacity of 262 acre-feet, providing essential protection for the surrounding area.
Maintained by the local government and regulated by the West Virginia Division of Water and Waste Management, Harmon Creek No. 2 Dam has a high hazard potential but is currently rated as satisfactory in condition. The dam features an uncontrolled spillway and outlet gates, serving as a crucial line of defense against potential flooding events. With a moderate risk assessment rating, ongoing inspections and risk management measures help ensure the safety and effectiveness of this important water resource infrastructure.
With its strategic location and key role in flood protection, Harmon Creek No. 2 Dam serves as a critical asset for the community. Managed by local authorities and meeting state regulatory standards, this dam continues to play a vital role in safeguarding the area against potential water-related disasters. Enthusiasts of water resources and climate resilience will appreciate the engineering and operational aspects of this essential flood risk reduction structure.
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 Harmon Creek No. 2 Dam
Where does the data for Harmon Creek No. 2 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 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.
