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

- 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.

Numerous roads were closed throughout the county due to heavy rains and flooding along rivers, streams, and creeks. Most bridges on township roads were over-topped with water. At one time, 56 roads were closed throughout the county. State Highway 95 was closed in several locations. Other specific road closures included Old Highway 95 and County Roads S, X, and VV. Lowland flooding occurred across much of the county, while many roads, trails, and campgrounds in the Black River State Forest were closed. Pigeon Creek was flooded and the Pigeon Falls Dam incurred some damage. Parks around Merrillan were all flooded, and the baseball field in Hixton was completely underwater. A person…

Runoff from heavy rain pushed the Black River out of its banks in Black River Falls. The river crested over thirteen feet above the flood stage at 60.3 feet, which was the 3rd highest crest on record at the time. The hydroelectric dam lost a gate when a large tree traveled through it. Several boats and docks that broke away on Lake Arbutus also traveled through the dam.

- Sep 6, 2015Flash Flood$400,000
National Weather Service narrative
Flood waters from Schoolhouse Creek caused U.S. Highways 10 and 12 to be closed in the extreme northern part of Jackson County east of Price. Numerous other roads were washed out with general flooding across the northern sections of the county covering much of the Townships of Cleveland and Garfield. Two accidents occurred when the drivers attempted to drive their vehicles over water covered roads that had been washed out. Three residents were stranded when flood waters overtook a dead end road in the Town of Cleveland. There were no reports of damage to private property with the damage limited to roads.

National Weather Service narrative
Locally heavy rains pushed the Black River at Black River Falls out of its banks from September 23rd to the 27th. The river exceeded the flood stage by over fourteen feet, cresting at 61.46 feet. This crest established a new flood of record. Ironically the dam at Black River Falls was being reconstructed during this event and was not in place during the peak. An early damage estimate of $600,000 was lowered to $110,000 at the dam by the utility and local contractor. From the evening of the 23rd to the afternoon of the 24th, 80 homes in the city of Black River Falls were evacuated.

Local officials estimated the value of the home and contents at just over $200,000.
- Jun 1, 2000Flash Flood$116,000
National Weather Service narrative
Localized flash flooding occurred as 2 to 3 inches of rain fell in less than two hours. Law enforcement officials reported a few county roads near North Bend (Jackson County) were washed out.
