Three people died and seven others were rescued Friday after a boat capsized in Geneva Lake as a strong storm passed through southern Wisconsin, an official said.

Many injuries were reported in Wisconsin’s Walworth County after the storm toppled trees, knocked down power lines and damaged buildings, said Tom Hausner, undersheriff for the Walworth County Sheriff’s department.

Hausner said he did not know any other information about the people who died and those rescued.

Police in the city of Lake Geneva are investigating, Hausner said. Officials there didn’t immediately respond to an email and voice message from The Associated Press seeking more information.

Lake Geneva Mayor Todd Krause declared an emergency and said that one person had minor injuries after being struck by a falling tree. Several areas of the city were experiencing power outages, he said in a statement.

Hausner said county authorities received multiple 911 calls reporting damage and people trapped in buildings and seeking help. He said deputies responded immediately but were delayed by downed power lines and trees blocking streets.

This tragic incident highlights the dangers of severe summer storms, which can quickly turn a peaceful day on the water into a deadly situation. The capsizing on Geneva Lake, combined with widespread damage across Walworth County, underscores how powerful weather events can overwhelm communities with little warning.

As investigations continue and recovery efforts begin, the focus remains on the families affected by the loss of life and the broader impact on the region. The storm’s destruction serves as a reminder of the need for preparedness and caution during severe weather, especially in popular recreational areas like Lake Geneva.
