How Lander County floods

Flash floods and general floods split the recorded flood history in Lander County, with flash flooding representing the slight majority of events over the last 30 years according to the NOAA Storm Events Database.

Recent history includes an atmospheric river event in March 2023 that brought high winds and rain-to-snow transitions, causing extensive flooding and an estimated $5.5 million in damages near the town of Austin at the Yomba Tribe. Additionally, a cutoff low pressure system produced multiple days of heavy rain, gusty severe winds, hail, and flooding in September 2023. Federal flood insurance records show minimal historical claim activity, limited to Zone A with an average payout of $1,058 and an average recorded water depth of 0 inches, alongside a single claim in an unknown zone with a $0 payout and an average recorded water depth of 0 inches.

Homeowners and real estate professionals should pay the most attention to properties located within FEMA Zone A, as well as areas susceptible to sudden heavy rainfall and runoff events near communities like Austin.

Flood insurance in Lander County

If a building in Lander 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.
