Patterson Creek No. 49 Dam dam
Patterson Creek No. 49 Dam
Patterson Creek No. 49 Dam, located in Grant, West Virginia, was completed in 1966 and is owned by the local government. The dam, designed by USDA NRCS, serves the primary purpose of flood risk reduction on Patterson Creek. It is an earth dam with a height of 48 feet and a hydraulic height of 43 feet, providing a maximum storage capacity of 462 acre-feet and a normal storage of 32 acre-feet. The dam spans 750 feet and covers a surface area of 7 acres, with a drainage area of 2.27 square miles.
This high hazard potential dam on Patterson Creek is regulated by the West Virginia Department of Environmental Protection and undergoes regular inspections. The dam has an uncontrolled spillway and outlet gates, with a condition assessment that is currently not rated. The Emergency Action Plan (EAP) was last revised in May 2014, and the dam is considered to have a moderate risk level. The risk management measures and inundation maps for the dam are currently not available, and there are no associated structures with the dam.
Overall, Patterson Creek No. 49 Dam plays a vital role in mitigating flood risks in the area and is closely monitored to ensure the safety of the surrounding communities. The dam's historical significance and its impact on water resources and climate in the region make it an essential infrastructure for water resource and climate enthusiasts to study and appreciate.
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. 49 Dam
Where does the data for Patterson Creek No. 49 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.
