Flash flooding from summer thunderstorms dominates the flood profile of Dundy County, Nebraska, accounting for twelve events alongside six general floods recorded over the last thirty years. Recent storm activity highlights this threat; on May 31, 2024, prolonged heavy rain from storms moving out of eastern Colorado caused minor urban flooding, while storms on May 17, 2023, dropped 1 to 1.5 inches of rain and caused flooding along the Republican River that covered miles of train tracks and shut down train operations. Additionally, severe weather on June 2, 2024, brought flash flooding to southeast Dundy County that left roads impassable, accompanied by damaging winds up to 100 mph and golf ball size hail.
Historical National Flood Insurance Program records for the county reflect minimal claims activity, with a single recorded claim in Zone A resulting in an average payout of $3,019 and an average recorded water depth of 1 inch. Properties near rivers, creeks, and low-lying areas prone to flash flooding or urban runoff should pay the most attention to local flood risks, particularly during severe convective storm events.

Flood · May 31, 2024. In the late afternoon of the 30th, storms began to fire across eastern Colorado and moved northeast through southwestern Nebraska. Later in the night, another round of storms moved east through the area. These rounds of storm produced heavy, prolonged rain, causing minor urban flooding to occur.
Flood · Jun 2, 2024. Thunderstorms developed across southwest Nebraska which led to some flash flooding in southeast Dundy county where some roads became impassable. Damaging winds around 100 mph were recorded across the area, along with some damage to trees, a building losing its roof, broken power lines, and a flipped pivot. Hail up to golf ball size also occurred.
Flood · May 26, 2023. In the afternoon of the 25th, slow moving, high precipitation thunderstorms formed in eastern Colorado and moved northeast. In the evening, severe hail was reported along with heavy rain. Overnight on the 25th, the storms slowed, began to back-build, and cause flooding in southwest Nebraska. Flooding continued until the 28th but the damage it caused took even longer to repair. 6.5 to 9.5 inches of rain was reporte…

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