The St. Clair County sheriff says a man has drowned on Weaubleau Creek near Collins after falling off an air mattress he was using as a raft.
Deputies found Bradley Dill, 21, on the river bank Monday night.
Investigators say Dill and a friend were riding down the bank tied together at the wrist, when the air mattress came out from under them.
Dill died on the way to the hospital.
