About this dam

Polk Creek No.8

Polk Creek No.8, also known as Wolfpen Lake, is a significant earth dam located in Lewis, West Virginia, with a primary purpose of flood risk reduction. Constructed in 1963 by the USDA NRCS, this dam stands at a height of 57.8 feet and has a maximum storage capacity of 342 acre-feet. With a hazard potential classified as high and a satisfactory condition assessment as of April 2013, this dam plays a crucial role in protecting the surrounding area from potential flooding events.

Managed by the local government and regulated by the West Virginia Department of Environmental Protection, Polk Creek No.8 is subject to regular inspections to ensure its structural integrity and safety. The dam has a drainage area of 0.74 square miles and a maximum discharge capacity of 6261 cubic feet per second. Despite its high hazard potential, the risk assessment for Polk Creek No.8 is classified as moderate, indicating that the dam is well-maintained and poses a manageable level of risk to the area it protects.

In the event of an emergency, Polk Creek No.8 does not have an established Emergency Action Plan (EAP) as of the latest data update in January 2015. However, the dam's emergency contacts and risk management measures are yet to be determined. With its uncontrolled spillway and outlet gates, Polk Creek No.8 serves as a critical infrastructure for flood control in the region, highlighting the importance of ongoing monitoring and maintenance to ensure the safety of the surrounding community and water resources.

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.

FAQ

About Polk Creek No.8

Where does the data for Polk Creek No.8 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.
