The storm downed hundreds of trees and power lines, damaged several buildings and created hazardous boating conditions on Geneva Lake. One boat with 10 people on board overturned and ultimately sank. 

Six adults and one child were rescued from the water, while three of the kids were missing when emergency responders got there. Those three children were found and later died despite life-saving attempts.

What happened on Geneva Lake?

Dig deeper:

Law enforcement said the boat operator had "extensive boating experience" and was unable to find safe harbor when the storm hit. At least two large waves broke over the bow, causing it to take on water. Another wave hit the side of the boat, causing it to roll, capsize and sink. 

The sunken vessel was found in 32 feet of water, and three children were found inside the boat. Divers were able to get them out and bring them to the service, and they were pronounced dead despite life-saving attempts. Investigators determined they had no external injuries and drowned.

What's next:

The Wisconsin Department of Natural Resources and Geneva Lake Law Enforcement Agency are still conducting a joint investigation into the accident. Eleven other agencies assisted with the immediate needs.
