Lake Delton, the town this property stands in, in 43 storm reports between 1994 and 2025: 23 thunderstorm wind, 12 hail, 2 tornado, 2 flood.
The reports record 1 injury. Each account below is quoted exactly as the forecast office
filed it, from the NOAA Storm Events Database, and each date
opens the federal record of that event.
Sauk County experienced 4 flash flood events over a 3-day period. Two of the events started on June 7th, one on June 8th, and the last one on June 9th. In each case, flash flooding caused home and business damage as well as crop losses. Roads were blocked or washed out (STH 154 and CTH C), and bridges were damaged. Many vehicles stalled. Locations in the Baraboo River Valley sustained considerable damage as the river crested at all-time levels. Collectively, each of these 4 flash floods resulted in home and business damage along with some crop losses. It was nearly impossible to break down the damages by flash flood event. Therefore, the collective breakdown is provided in the June 9th StormData entry for Sauk County.||On June 9th, the levee holding back Lake Delton eroded over a 5 hour periiod and eventually broke (the actual dam held), allowing Lake Delton to empty into the Wisconsin River. A 300-foot section of CTH near the breach was washed away. At least 4 homes were washed away, and damage was inflicted on boats and piers. There were no injuries or fatalities.||The breakdown for residential home losses for the 3-day period were: over 800 minimally affected, 45 with major damage, and 31 destroyed (total of $19.2 million for home losses). Business losses are estimated to be about $1 million. Crop losses were estimated at $15 million. Public sector damage was about $2.25 million. Several roads and bridges sustained damage.
This tornado segment is the 2nd of a three-segment tornado (Columbia-Sauk-Columbia). The first segment started in Columbia County about 3.0 miles east of Wisconsin Dells. This second segment entered Sauk County about 8.5 miles east-southeast of Lake Delton at 1813CST (or about 0.6 mile northeast of the intersection of N Hein Rd. and Levee Rd.) and headed southeast. It exited Sauk County about 10.1 miles east-southeast of Lake Delton at 1817CST where Levee Rd. goes east into Columiba County. The tornado caused a tree to fall onto a home which caused 1000 dollars in property damage. The tornado during this second county segment had weakened a bit down to the F0 rating with winds of 35-63 knots (40-72 mph). Overall, this three-segment tornado path length was 16.9 miles with a time span of 1754CST to 1840CST.
