Nebraska flood risk is often concentrated near the Platte River, Missouri River, Elkhorn River, Salt Creek, Loup River, Republican River, Big Blue River, and low-lying drainage areas.
Some of the more important Nebraska flood insurance markets include Omaha, Lincoln, Bellevue, Fremont, Columbus, Grand Island, North Platte, Norfolk, Kearney, Plattsmouth, Schuyler, and river-adjacent communities. The 2019 flooding showed how quickly Nebraska risk can change when snowpack, frozen ground, rain, and river systems combine. USGS describes the 2019 event as heavy flooding along the Missouri River and its tributaries throughout Nebraska and Iowa.
Flood Nerd POV: The flood map is useful, but Nebraska risk is watershed-driven. A property can be “near enough” to matter even when it does not feel like a riverfront home.
