How Goshen County floods

Flash flooding from summer thunderstorms dominates the flood risk profile in Goshen County, Wyoming, backed by 34 recorded flash flood events over the last 30 years. Recent occurrences include heavy rainfall in July 2024 that caused flash flooding in central Goshen County and Torrington, leaving portions of Highway 26 underwater. Additionally, heavy rain in June 2023 produced flash flooding across the plains and near Chugwater, as well as from Hawk Springs to La Grange in the southern part of the county.

National Flood Insurance Program records show claims filed across different zones, including five claims in Zone A with an average payout of $3,490 and an average recorded water depth of 2 inches. Zone X also recorded five claims, with a higher average payout of $18,552 and an average recorded water depth of 1 inch, alongside two claims in Zone UNKNOWN with an average payout of $0 and an average recorded water depth of 0 inches.

Homeowners, real estate agents, and journalists should pay the closest attention to properties located within mapped Special Flood Hazard Areas like Zone A, as well as properties in Zone X where significant claim payouts indicate financial risk from localized heavy rainfall and storm events.

The zones you’ll see on the map

Flood insurance in Goshen County

If a building in Goshen County is in a high-risk zone (A or V) and its mortgage comes from a federally regulated or insured lender, or is federally backed, flood insurance is required.

Outside those zones it is optional, and often worth having: from 2014 to 2024 nearly one-third of NFIP claims came from outside the high-risk Special Flood Hazard Area. Since Risk Rating 2.0, NFIP premiums are set for each building, so the only reliable price is a quote: FloodSmart.gov or a local agent.
