ANCHORAGE - A boat carrying five people flipped on the Kenai River and a man was missing and presumed drowned over the weekend, according to Alaska State Troopers.
The missing man is 56-year-old David Yanoshek of Anchorage.
Troopers spokeswoman Megan Peters said Yanoshek on Saturday was wearing hip waders but no lifejacket.
The boat tipped about two miles upriver from Skilak Lake and searchers were concentrating in the area downriver of Jim's Landing.
Peters said Yanoshek was with a party of 30 to 35 people.
Troopers received a call about the incident at 5:20 p.m., about an hour after the boat flipped.
Four others on the boat made it ashore.
The river below Jim's Landing is known as the Kenai Canyon and is popular with rafters and kayakers.
