When	Event	Place named	Harm	What the report says
December 2015	Flood	Augusta	$2,300,000	Between 7 and 11 inches of rain fell across St. Charles County during a 2 day period. All of this rain caused the creeks and rivers to rise. The Missouri and Mississippi Rivers went into major flood as well as Dardenne Creek. Almost 300 structures were either damaged or destroyed from the river flooding, with St. Peters and St. Charles being the worst hit areas in St. Charles County. Damage estimates so far were around $2.3 million.
May 2007	Flood	Augusta	$2,000	The Missouri River flooded parts of the southern border of St. Charles County from Agusta to the Mississippi River. Frontier Park in St. Charles flooded, otherwise flooding was limited to some farmland and a few roads along the river.
July 2023	Thunderstorm Wind	Augusta	-	Thunderstorm winds blew down numerous tree limbs along Highway 94, especially between Augusta and Definance.
August 2019	Flash Flood	Augusta	-	Up to five inches of rain fell in the southwestern portions of St. Charles County causing flash flooding. Femme Osage Creek Road had portions of it washed out due to flash flooding between Cappeln Osage Road and Becker-Joerling Road.
May 2019	Tornado (EF1)	Augusta	-	After crossing the Missouri River into St. Charles County, the tornado uprooted and snapped off numerous trees on Sanders Road and caused extensive damage to a farm outbuilding. Further northeast as it crossed Terry Road, where it caused extensive tree damage. As it continued northeast it caused minor structural damage on a barn and outbuilding on Coates Lane, before causing minor roof damage to a house as well as snapping off several trees. The tornado lifted and dissipated just southeast of the intersection of Coates Lane and Duke Road. This portion of the tornado was rated EF1 with a path length of 4 miles and a max path width of 250 yards.

January 2016	Flood	Augusta	-	Missouri River remained at moderate flood stage through midday on January 2nd. The flooding was a result of record rainfall in late December.
December 2015	Flood	Augusta	-	The flooding persisted across St. Charles County on December 27th and 28th. Numerous roads remained flooded. Interstate 70 had to be shut down between exits 220 and 222 because Dardenne Creek rose 6 feet above flood stage in St. Peters (DRCM7). This caused the Interstate to be flooded by several feet of water. The highway was shut down both directions around Noon on December 27th. Westbound I-70 was reopened at 645 am and eastbound was finally reopened at 130 pm on December 28th.
September 2012	Thunderstorm Wind	Augusta	-	Thunderstorm winds snapped a foot and a half diameter oak tree about 15 feet up from its base.

The tornado crossed the Missouri River into extreme northeast Franklin County. The width ranged from 50 to 200 yards. Maximum damage, noted at several locations along the path, was estimated at EF1. Some of the more significant damage included the total removal of a roof from a century old home at the Balducci Winery, significant tree and home damage 1 to 2 miles east of the winery, large trees snapped at a catholic church 1 mile northwest of Augusta, and structural damage to a home just northeast of Klondike Park.
