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

Days each year on which a satellite-traced plume of medium or heavy smoke covered the county’s population centre, 2011 to 2025.
  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.

Months each year with a Palmer index of −3 or lower, 1895 to 2025. Twelve means the whole year.
  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).

  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.

  1. Apr 4, 1997Ice Storm, Sargent$6.0 million
    National Weather Service narrative

    An intense low pressure system, with center pressures around 28.8 inches, tracked from Fergus Falls to International Falls, Minnesota. The initial rain was accompanied by lightning and thunder in southern Grand Forks county, and then changed to freezing rain as the temperature dropped. One-half to 2 inches of ice built up on exposed surfaces. Hundreds of power poles and lines snapped due to the weight of the ice, cutting power to many homes and businesses, many of which were beginning to fight the spring flood. The wind reporting systems on the AWOS and ASOS sites across eastern North Dakota froze in place, remaining out for 7 days. The three inches of liquid equivalent from the…

  2. Apr 5, 1997Blizzard, Sargent$6.0 million
    National Weather Service narrative

    With falling temperatures on the back side of the low, the freezing rain turned to ice pellets and then to snow. A strong pressure gradient created winds up to 65 mph, dropping visibilities down to zero. The strong wind, on top of heavy ice accumulations, caused thousands of power poles to snap. This cut power to over 100,000 people in eastern North Dakota and northwest Minnesota and resulted in $30 million in damages just to the power infrastructure. A 2,060 foot television tower collapsed near Galesburg on April 5th. With power cut, many people had to seek shelters with generator power in order to keep warm. Some smaller communities were without power for more than a week. Most…

  3. Jul 10, 2011Tornado$800,000
    National Weather Service narrative

    This tornado was enshrouded in downburst winds and heavy rains, but was briefly visible to spotters near Cogswell. The tornado ripped out nearly seven miles of dual wooden high voltage power line along its track. Numerous trees and singular power poles were snapped and pole sheds and steel grain bins were destroyed at multiple locations. Peak winds were estimated at 120 mph.

  4. Jul 20, 2003Thunderstorm Wind$500,000
    National Weather Service narrative

    Three of four 44,000 bushel grain bins were blown over at the Crete Elevator complex. The fourth, which was full of grain, remained standing. Eight 40,000 bushel grains bins were also damaged and one 40,000 bushel grain bin was blown down.

  5. Jul 3, 2003Thunderstorm Wind$400,000
    National Weather Service narrative

    Two 30,000 bushel grain bins were destroyed by the strong wind. The tops of two 4,000 bushel grain silos were damaged. A flag pole and large trees were blown over. Ten homes had broken windows, damaged siding, and damaged roofing.

  6. Jul 10, 2011Thunderstorm Wind$250,000
    National Weather Service narrative

    Numerous tree limbs were broken down around town. Fields were flattened by wind or stripped bare by wind driven hail. Wind damage occurred throughout Rutland and Dunbar townships from the 80 mph gusts.

  7. Jul 10, 2011Thunderstorm Wind$250,000
    National Weather Service narrative

    Several houses lost shingles or had siding or roofing damages. Numerous large trees and tree limbs were broken down around town. Widespread wind damage was evident throughout Bowen and Forman townships.

  8. Jun 24, 1998Flood, Sargent$250,000
    National Weather Service narrative

    8 inches of rain in a week brought numerous flooding problems to the cities of Forman and Cogswell. Many homes had to be sandbagged to protect them from the overland flooding. One trailer park in Forman was evacuated, as water 3 to 5 feet deep poured in. This caused 17 residents to be evacuated. Cogswell residents were without drinking water, as a lift station flooded. Water covered the main street of Cogswell 16 inches deep. Highway 11 from Forman to Lidgerwood was closed due to high water. The National Guard was called in to assist local officials. Several basements were in danger of collapse from the groundwater pressure.

  10. Apr 1, 2006Flood$245,000
    National Weather Service narrative

    Water tables remained high across Sargent County after substantial rainfall in 2005. Many roads and bridges were damaged and vehicles were getting stuck on soft rural roads. Several residents reported water in their basements. Sargent County received a Presidential Disaster Declaration for damages caused by spring flooding.
