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

- 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.

- 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).

- Jul 19, 2015Flash Flood$300,000
National Weather Service narrative
Several rounds of slow moving thunderstorms produced heavy rainfall amounts of 3.00 to 7.00 inches of rain in Scott County during the early morning of July 19th. This area was already saturated from flooding which occurred one week prior. Thus, flash flooding quickly developed which flooded most rural roads in the county. In addition, roads were washed out and mudslides were reported from Winchester through Naples to Bluffs.
- Jun 10, 2011Thunderstorm Wind$200,000
National Weather Service narrative
Several trees and tree limbs were blown down in Winchester. In addition, 15 large power poles were snapped, resulting in a widespread power outage.
- Apr 8, 1999Tornado$150,000
National Weather Service narrative
As the tornado crossed the Illinois River from Pike County into Scott County, it caused extensive damage to a residence next to a pump house located near the river, 5 miles southwest of Oxville. The windows on the west side of the house were blown out and the east wall was blown out as well. Shortly after hitting the home the tornado lifted and dissipated. No injuries were reported and the damage was estimated around $150,000.
- Apr 8, 1999Tornado$100,000
National Weather Service narrative
A tornado developed 0.3 of a mile north northwest of Oxville. It took the roof off of a trailer then continued to the northeast. One mile northeast of Oxville, it destroyed a barn and three grain bins. It destroyed numerous trees and caused damage to several barns and silos before lifting and dissipating 3 miles southeast of Bluffs. No injuries were reported and damage was estimated around $100,000.
- Dec 8, 2007Ice Storm, Scott$100,000

- Jun 19, 2011Flash Flood$100,000
National Weather Service narrative
A levee on the Mauvaise Terre Creek near Oxville broke in three places due to rapid streamflow from flooding upstream in Morgan County, and renewed heavy rain. The resulting flooding inundated State Route 100 north of I-72, covered nearly 2,000 acres of crops with water, and closed roads in and out of Oxville. ||An 84 year old woman drove her car into the flood waters of the Mauvaise Terre Creek just before the levees failed. She was rescued and uninjured, but her car was damaged.
- Jun 3, 2008Hail$85,000
