The Flooding Character of Gilmer County

Flash flooding from heavy rainfall events is the primary flood concern in Gilmer County, WV. Over the past 30 years, NOAA Storm Events data shows 28 flash flood events and 26 flood events. Recent examples include widespread rainfall causing creeks and streams to overflow their banks on January 31, 2025, and river flooding that persisted into February 1, 2025, along the Little Kanawha River.

National Flood Insurance Program (NFIP) data indicates that properties in Zone A, which typically represent areas of higher flood risk, have experienced the most claims, with an average payout of $9,571 and an average water depth of 6.1 feet. However, properties in Zone X and even those with an unknown flood zone designation have also seen significant claims with higher average payouts and water depths, suggesting that flood risk is not confined to designated high-risk areas. Homeowners in low-lying areas, near creeks and streams, and those without elevated foundations should pay particular attention to flood risk.
