An Opelousas man drowned Saturday afternoon while tubing on the Amite River near Watson.

Ketni Thomas, 32, was tubing on the river about 3 p.m. Saturday when he swam upstream to help a younger tuber in distress, Livingston Parish Sheriff Jason Ard said in a news release.

Thomas became exhausted and went underwater. He was unresponsive when deputies were dispatched.

An investigation is ongoing.

Several people have drowned while floating on inner tubes on the Amite River in recent years, including two men last July.
