Polk Creek No.7 dam
Polk Creek No.7
Polk Creek No.7, also known as Dry Fork, is a key water resource in Lewis, West Virginia, managed by the local government with design assistance from USDA NRCS. This earth dam, completed in 1967, stands at a height of 52.3 feet and serves primarily for flood risk reduction along the Dry Fork river. With a storage capacity of 762 acre-feet and a drainage area of 1.41 square miles, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
The dam's spillway type is uncontrolled, and it has a high hazard potential, as indicated by a risk assessment rating of moderate (3). Despite this, the condition assessment in 2013 deemed the dam to be satisfactory. Regular inspections are conducted every two years to ensure its structural integrity and effectiveness in flood control. While the dam has not been modified in recent years, it remains a vital component of the water management infrastructure in the region.
With a satisfactory condition assessment and a history of successful flood risk reduction, Polk Creek No.7 stands as a testament to effective water resource management in West Virginia. Its strategic location and design, coupled with regular inspections and maintenance, ensure that the dam continues to serve its primary purpose of safeguarding the community against potential flooding events along the Dry Fork river. As climate change continues to impact water resources, dams like Polk Creek No.7 play a crucial role in mitigating the risks associated with extreme weather events.
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 Polk Creek No.7
Where does the data for Polk Creek No.7 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.
