How Lincoln County floods

Flash flooding from summer thunderstorms dominates the flood history of Lincoln County, Nebraska, accounting for 39 of the 58 total flood events recorded over the last 30 years by the NOAA Storm Events Database.

Recent storm events illustrate this hazard. On July 29, 2025, widespread thunderstorms dropped 1 to 3 inches of heavy rain across the area, leading to flash flooding in the North Platte region. Earlier, on July 23, 2025, severe storms tracked east from Keith County into Lincoln and Custer Counties during the evening hours. Spring events also occur, such as the thunderstorms on May 15, 2021, which brought high winds and heavy rain following earlier regional flooding in March 2019 caused by snowmelt and rain on frozen ground.

National Flood Insurance Program records show the highest concentration of claims in Zone A with 59 claims averaging $7,728 per payout and an average recorded water depth of 4 inches. Zone X accounts for 6 claims with an average payout of $15,223 and an average recorded water depth of 1 inch, while Zone UNKNOWN records 11 claims averaging $524 with an average recorded water depth of 0 inches. Homeowners and real estate agents with properties located within Zone A and Zone X should pay the most attention to flood risk given these historical claim patterns and the frequency of intense summer flash floods.

The zones you’ll see on the map

Every colour on the map above is a place on this drawing: where the ground sits relative to the flood FEMA plans for.

Flood insurance in Lincoln County

If a building in Lincoln 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.
