About this disaster type

Understanding flood declarations

FEMA has issued 10,575 county-level disaster declarations classified as flood, affecting 2,613 counties across 49 states. Combined public and individual assistance obligations for this disaster type total $11.9B.

The states with the highest concentration of flood declarations are Iowa, Minnesota, and North Dakota. Each state page links to county-level detail pages where the specific timeline and spending breakdowns for flood events can be reviewed.

A disaster declaration is a formal determination by the President (or FEMA administrator for emergency declarations) that federal assistance is needed. Not every natural event results in a declaration — the state must request one, and FEMA evaluates the damage relative to state and local capacity. The declaration count on this page reflects the number of county-level records in the federal datasets, not the number of individual storms or events.
