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

  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.

  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.

    National Weather Service narrative

    Hail up to golfball-size fell in the Schuyler area for around 20 minutes. The hail caused considerable damage to houses, vehicles and trees in town. The ground was almost completely covered white with hail and hail fragments. An insurance agent stated the damage was in the millions of dollars.

  2. Jun 11, 2010Flood$1.5 million
    National Weather Service narrative

    Heavy rain from roughly June 7th into the 14th produced prolonged flooding along Shell Creek and its tributaries from near Lindsay in Platte county downstream to around Schuyler in Colfax county. The high water flooded many county roads and forced the closure of Highway 15 north of Schuyler for a while. Shell Creek or one of its tributaries also flooded sections of northeast Schuyler prompting homes and businesses to sandbag to try to limit the damage. Nonetheless, some damage to about 200 homes and businesses occurred anyway, mostly to basements. Damage was also noted to county roads and crops because of the prolonged period of high water. Emergency management reported that at…

  3. May 30, 2008Flood$1.0 million
    National Weather Service narrative

    Heavy rain which fell on May 29th eventually worked its way down Shell Creek to just northeast of Schuyler overflowing into a tributary which flooded the northeast section of town late on May 30th. The flooding continued into Saturday, May 31st and forced the evacuation of some people in town. The water mostly flooded basements and garages, but it also affected the main floors of a few homes and several businesses. In all 250 homes and buildings were damaged and 8 families were permanently displaced. The water reached 4 to 5 feet deep on a few streets. Just north of town the flood waters crossed Highway 15 for a while. The dollar damage due to flooding in town and the surrounding…

    Damage to 10 farmsteads and a 100 year old historic church.

  5. Aug 4, 1996Flood, Colfax$500,000
    National Weather Service narrative

    Heavy rains fell in Colfax County, filling streets and resulting in damage to crops and roads. Nearly 8 inches of rain was reported at Schuyler. Thunderstorms redeveloping over the same area and abundant tropical moisture produced the heavy rains.

  6. Mar 13, 2019Flash Flood$170,000
    National Weather Service narrative

    A levee on Shell Creek was topped by waters from heavy rain and fast snow melt. This caused the town of Rogers to be flooded. The town was evacuated in anticipation that water would enter the town.

  7. May 22, 1996Thunderstorm Wind$50,000
    National Weather Service narrative

    Thunderstorm winds damaged the roof of the Co-op in Richland, a camper, outbuildings, and several businesses in Schuyler. Several signs and windows were broken.

  8. Aug 16, 2017Flash Flood$50,000

    Highway 15 was closed near the Platte River Bridge along with several county roads.

  9. Aug 16, 2017Flash Flood$50,000

    Flash flooding occurred along Highway 30 near Richland and along Highway 15 near Schuyler.

  10. Apr 5, 2009Winter Storm, Colfax$23,000
    National Weather Service narrative

    Rain changed to a brief period of freezing rain then to a heavy wet snow around midnight CDT on April 5th and continued into the mid morning hours of that day. The precipitation was accompanied by north winds of 25 to 35 mph with gusts to 50 mph. Although snowfall ended during the late morning of the 5th, the strong winds caused continued drifting snow in open areas into the afternoon hours. The accumulated ice and heavy wet snow caused scattered power outages across the county and caused localized damage. In Schuyler a grandstand roof was damaged and a section of a fence was blown down resulting in over $20,000 in damage. Snow amounts were between 4 and 8 inches across the county…
