About this dam

Patterson Creek No.15

Patterson Creek No.15, also known as Mike's Run, is a local government-owned dam in West Virginia designed by the USDA NRCS. Completed in 1965, this earth dam stands at a height of 85 feet and serves primarily for flood risk reduction. With a maximum storage capacity of 5,799 acre-feet and a normal storage of 149 acre-feet, it covers a surface area of 25 acres and drains an area of 17.81 square miles.

Located in Burlington, Mineral County, this dam on Mike's Run is regulated by the West Virginia Department of Environmental Protection and is subject to state permitting, inspection, and enforcement. The dam's spillway is uncontrolled, and its hazard potential is rated as high. Despite being in moderate risk, the condition of the dam is not rated, highlighting the importance of ongoing monitoring and maintenance to ensure public safety in the event of an emergency.

While the dam has not been modified in recent years and lacks a formal Emergency Action Plan (EAP), its risk management measures and inundation maps remain underdeveloped. With a designated inspection frequency of every two years, stakeholders must work towards enhancing the dam's safety protocols and preparedness to mitigate potential risks and safeguard the surrounding community and environment.

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.

FAQ

About Patterson Creek No.15

Where does the data for Patterson Creek No.15 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.
