- Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Benton County: 0.
- 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.

- 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.

- 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.

- 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).
- 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).

Costliest events since 1996
- Jun 20, 2007Hail$3.0 million
National Weather Service narrative
Hail damaged many houses and vehicles, and area crops. The hail fell when winds were not too strong, so crop damage was limited.
- Apr 7, 2001Flash Flood$3.0 million
National Weather Service narrative
The same intense low pressure system that brought high wind to southern Minnesota also dumped a large area of 3 to 4 inches rain across west central and central Minnesota, on top of melting snow and saturated ground. Drainage ditches, still clogged with snow, were unable to accept most of this rain water. About 3000 homes in Stearns County and 500 homes in Benton County sustained water damage to basements. Several homes were flooded along Hawk Creek near Clara City (Chippewa County), as were about 50 homes in Chokio and Morris (Stevens County). Dozens of people were evacuated, though no injuries were reported. Hundreds of roads were submerged and some bridges flooded.
- Jul 1, 2011Thunderstorm Wind$1.5 million
National Weather Service narrative
A severe downburst wind event occurred from Sauk Rapids, north and northeast across a large swath of central and northern Benton County. Hundreds of trees were toppled, broken or pushed over. Many trees landed on houses, sheds and vehicles.
- Apr 22, 2001Flash Flood$500,000
National Weather Service narrative
Two to four inches rain fell on saturated ground. The most severe damage occured in Santiago (Sherburne County), where a dike along County Road 11 gave way and allowed water to come crashing into town. About one dozen homes and businesses were flooded and evacuations were necessary. Other damage included flooded basements in Foley (Benton County) and Milaca (Mille Lacs County). County officials reported roads closed in portions of Benton, Meeker, Redwood, Renville and Stearns Counties, with some roads washed out. Intersections were flooded in Willmar (Kandiyohi County).
- Aug 28, 2021Hail$250,000
National Weather Service narrative
There were multiple vehicles damaged with windows broken. In addition, siding on houses was damaged and numerous windows were broken to houses and outbuildings in and around Popple Creek.
- Jul 27, 2002Thunderstorm Wind$250,000
National Weather Service narrative
Roof off house. House was also moved 5 feet off its foundation. Trees down. Sheds and pole barns down.
- Jun 21, 2013Thunderstorm Wind$200,000
National Weather Service narrative
A barn was blown down near Gilman. In addition, numerous trees were blown down around the area.
- Aug 28, 2021Hail$100,000
National Weather Service narrative
Severe thunderstorms that developed across South Dakota early Saturday morning, August 28th, quickly moved into west central Minnesota and produced up to 3 diameter hail in Swift County. These storms congealed into a fast moving bow-echo that surged across parts of central Minnesota, between Willmar, St. Cloud and Mora. Several areas received very large hail, severe wind gusts and straight-line winds, and there was one tornado south of Albany. As the storms moved over east-central Minnesota, the severity of the storms lessened and only produced isolated wind damage around Milaca. The worst damaged areas were near Glenwood, Sauk Centre, and north and east of St. Cloud where…
- Jul 10, 2002Flash Flood$100,000
National Weather Service narrative
Seven to ten inches of rain was common across a large swath of Benton County, from the northwest corner to the southeast. About 30 roads were closed, including State Highway 23 in Foley. A few township roads were washed out. About 3500 sandbags were used in the Foley area. Some basements were flooded. Local agriculture officials estimate that about 10% of the sellable crops in Benton County were destroyed. Numerous creeks in Alberta township (Gilman to Rum River area) rose out of their banks.
- Aug 13, 2010Thunderstorm Wind$50,000
National Weather Service narrative
Many hundreds, perhaps thousands of trees were uprooted, snapped or broken in an eight mile wide swath that extended from the western edge of the county, near Rice to Watab, to just north of Sartell, to north central Benton County, in Graham Township, centered near State Highway 25 and County Road 77. In addition, a local Minnesota Department of Transportation Weather Station near Rice, measured a wind gust of 64 knots. A semi-truck was blown over near Rice along Highway 10, resulting in one injury. Plus, a spotter on the northeast shore of Little Rock Lake measured a wind gust of 81 mph before his tower collapsed and the anemometer ceased to function. The intense wind blew from…
