- Injuries and deaths are for the tornado’s whole path, which may extend beyond this area.
- 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.

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.

- 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 city centre.
- 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).

- 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.

- Jun 18, 2008Flash Flood$500,000
National Weather Service narrative
A levee on the Mississippi River near Meyer failed and caused flash flooding in an area from Bear Creek northward toward the Adams/Hancock county line. The flood waters spread as far east as East 500th Street along the bluffs. A couple hours later a second levee break occurred aggravating the flooding situation. A couple dozen homes in Meyer were flooded as well as a couple of businesses. The entire town of 40 to 50 people had evacuated before the levee was breached.
- Apr 20, 2025Tornado$120,000
National Weather Service narrative
A weak tornado touched down along Hickman Road at 7:04 PM and destroyed an outbuilding with winds estimated as strong as 85 mph. It then moved northeast through Bailey Park and produced roof damage to another outbuilding along E 2400th Street near N 2150th Ave. The tornado continued to move northeast past Golden, IL and produced roof damage to multiple outbuildings along E 2700th Street between N 2500th Ave and N 2600th Ave before dissipating just north of N 2600th Ave at 7:10 PM. The tornado was rated EF-0 with a path length of 8.17 miles and a maximum path width of 100 yards.
