The Iowa Department of Natural Resources says two people were fishing on Saturday afternoon near the spillway of Lock and Dam #10. They were onboard a 14-foot flatboat in a restricted area and got into turbulent waters.
The DNR says a passenger 54-year-old Shaun Oppenheimer of Quasqueton was thrown overboard and drowned.
The other person wasn’t hurt. The DNR says neither was wearing a life vest though they had them onboard.
