FEMA has issued 16 declarations naming the county since 1967, 14 of them for natural hazards; the latest for a natural hazard was “Severe Winter Storm and Straight-Line Winds” on May 21, 2025.

When was the last damaging storm in Dakota County?

The most recent record with damage, injuries or deaths is the June 24, 2024 flood ($1.1 million in damage in 2025 dollars).

Rainfall amounts across Dakota County from June 20-22 were generally a half inch or less. However, farther north and upstream 6 to 10 plus inches fell across portions of southeast South Dakota and northwest Iowa. Record flood waters along the Vermillion and Big Sioux Rivers emptied into the Missouri River, pushing river levels into minor flooding. Missouri River flooding resulted in the evacuation of the Lower Scenic Park Campground and damage to parts of the park, including the soccer fields and some campground electrical pedestals. The police shooting range was also damaged. Preliminary damage assessments estimate loss to public infrastructure to be nearly 1.18 million dollars. For additional information on river flooding, please see other flood entries for Dakota County.

Is it getting more frequent?

Records per decade for Dakota County's most frequent hazards. Counts rose everywhere after 1996, when NOAA began recording every event type, so compare decades within a hazard's complete period only (the shaded cells come before it).

Dakota County: records per decade (the 2020s to June 30, 2026)

Drought in the 2020-26: 43 records against 11 in the decade before, 43 of them forecast-zone records. Cells marked z rose mostly through zone records. The local National Weather Service office files these once per forecast zone, so a change in how it draws its zones or splits a storm into records moves this count as much as the weather does; read it beside the Dakota County days with a record above.
