Patterson Creek No. 41 Dam dam
Patterson Creek No. 41 Dam
Patterson Creek No. 41 Dam, also known as North Fork Dam, is a vital water resource structure located in Grant, West Virginia. Built in 1969 by the USDA NRCS, this earth dam stands at a height of 88 feet and serves the primary purpose of flood risk reduction along the North Fork river. With a storage capacity of 7680 acre-feet and a drainage area of 29.53 square miles, the dam plays a crucial role in managing water flow and protecting the surrounding communities from potential flooding events.
Managed by the local government and regulated by the West Virginia Department of Environmental Protection, the dam is classified as having a high hazard potential due to its size and location. Despite not being rated for its condition, regular inspections are conducted to ensure its structural integrity. In the event of an emergency, measures are in place, although the Emergency Action Plan (EAP) may need updating. With a moderate risk assessment score, the dam continues to be a key component in the region's water resource and climate management efforts.
In conclusion, Patterson Creek No. 41 Dam stands as a critical infrastructure for flood risk reduction in West Virginia. With its strategic location, high hazard potential, and moderate risk assessment, the dam serves as a crucial element in safeguarding the local communities and natural habitats along the North Fork river. As water resource and climate enthusiasts, understanding the significance of this structure highlights the importance of sustainable water management practices and the need for ongoing monitoring and maintenance to ensure its long-term effectiveness.
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 Patterson Creek No. 41 Dam
Where does the data for Patterson Creek No. 41 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.
