Carver County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Carver County: 3.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

River crests

River gauges

1. Crests are the highest and the recent crests the National Weather Service lists for each river gauge in the county that has a flood stage, not every flood. Flood categories use each gauge's current flood stages; crests from before levees, dams or channel changes may not be comparable. Crests measured on an old datum are left out of the rankings.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

Mapped landslides

Mapped by USGS MN (259).

1. Landslides mapped in the USGS compilation of landslide inventories across the United States (version 3.0, 2025), rated probable or better. The compilation joins inventories made by federal and state agencies for different purposes and areas, so the number mapped in a county reflects how closely it has been surveyed as much as how often its slopes fail. An area with few records may simply not have been mapped. Deaths are as recorded in the inventories; a slide listed in two inventories is counted once.

   Several trained spotters reported numerous dime, up to baseball size hail from north of Watertown, southeast to the southeast part of Watertown. Damage was extensive to crops and homes throughout the area.

6. May 1, 2001Hail$500,000
7. Aug 9, 2020Hail$500,000
   National Weather Service narrative

   Numerous sources from social media pictures, to trained spotters and official NWS observations, reported and measured very large hail for nearly 40 minutes from Victoria, eastward to the Carver, Hennepin County line. This includes some of the smaller communities between the two towns. ||The largest hailstone was measured at 2.75 inches in diameter and fell near Victoria. Two inch hail was measured at the NWS office. Due to the large hail size and almost a continuous line of storms redeveloping in the same areas, many roofs and cars were damaged.

8. Jun 17, 2012Thunderstorm Wind$300,000
   National Weather Service narrative

   North of the city of New Germany, severe straight-line winds caused damage to five sheds, with two completely destroyed. In addition, three corn bins were damaged, one turned over, one was wrapped around a tree, and one damaged by another falling on it.

   A storm survey indicated that an EF-1 tornado touched down in Hollywood Township in Carver County. The tornado spun up seven miles west-southwest of Watertown and continued east-northeast to two miles west-southwest of Watertown. The most damage occurred as the tornado crossed Vega Avenue where numerous trees were snapped and some minor structural damage was found. An apple orchard was also damaged with this tornado. There was a private weather station that measured a 99 mph wind gust before it blew off the roof. The path length was 5.1 miles long with a maximum wind speed of 105 mph.

10. Jul 1, 2011Thunderstorm Wind$250,000
