I just checked, the Wisconsin Dells Duck Rides, that's how they spell it most likely to make it easier to understand for the tourist. is still operating. I remember my mom taking me to the Dells and riding them in 1964. The tragedy in the Ozarks was in 2018 and the DUKW's were brought back after a new company bought them "additional safety measures include captain visibility from all passenger seats, wider aisle ways, and an improved fire suppression system.
As well as removing the side curtains that were such a big part of what added to the 2018 tragedy.”
According to Wikipedia "The vessel was a refurbished DUKW built in 1944 and extended to hold more people, a design known as a "stretch duck". The first 911 call was received at 7:09pm as the boat was already going under the water, according to the local sheriff. Local officials reported the following morning that all passengers and crew aboard the vessel had been accounted for and confirmed a total of 17 deaths. The ages of those who died in the accident ranged from 1 to 70 years old, and nine were members of a single family visiting from Indianapolis. None of the passengers or crew were wearing a life jacket when the boat sank.
The accident occurred shortly after 7 p.m. Central Daylight Time on July 19, 2018, as a line of severe thunderstorms approached the Branson area. Approximately an hour prior to the accident, the National Weather Service had issued a severe thunderstorm warning for areas around the lake. It is not known whether the two crew members aboard the vessel were aware of the warning or what action they attempted to take. The National Weather Service reports that winds in the area at the time were in excess of 60 miles per hour (100 km/h), and the storm over the lake was moving very quickly and causing three-foot (one-meter) waves on the lake.
