Patterson Creek No.36 dam
Patterson Creek No.36
Patterson Creek No.36 is a crucial flood risk reduction structure located in Fort Ashby, West Virginia. Owned by the local government and designed by USDA NRCS, this earth dam stands at a height of 38 feet, with a hydraulic height of 34 feet. Completed in 1972, it serves the primary purpose of flood risk reduction along the Patterson Creek, with a storage capacity of 284 acre-feet and a drainage area of 0.97 square miles.
The dam has a surface area of 3 acres and a length of 330 feet, with a spillway type classified as "Uncontrolled." Despite its fair condition assessment back in 2014, Patterson Creek No.36 holds a high hazard potential due to its location and purpose. The risk assessment for this structure is moderate, with ongoing risk management measures to ensure its continued effectiveness in mitigating flood risks in the area. With state regulation and inspection in place, this dam plays a vital role in safeguarding the local community from potential flooding events.
Overall, Patterson Creek No.36 serves as a critical infrastructure for flood risk reduction in Mineral County, West Virginia. With its strategic location along the Patterson Creek and proper state regulation, this earth dam continues to play a significant role in managing floodwaters and protecting the surrounding areas. As climate change and water resource management become increasingly important, structures like Patterson Creek No.36 highlight the importance of investing in resilient infrastructure to adapt to changing environmental conditions and ensure the safety of communities at risk of flooding.
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.36
Where does the data for Patterson Creek No.36 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.
