A 20-year-old Bothell man drowned Wednesday while swimming in the Snoqualmie River at Carnation.

According to a report from the King County Sheriff, the accident was reported shortly after 3 p.m. August 15, near the 1500 block of West Snoqualmie River Road Northeast.

Sheriff’s Deputies and Eastside Fire and Rescue personnel responded.

Deputies say the man went swimming with a group of co-workers. At some point, the victim was unable to stay afloat and slipped under the water.

According to the report, two boaters kayaking down the river attempted to pull the man up and out of the river, but the water was too deep.

An Eastside surface rescue pulled him from the water, and CPR was attempted. The man was taken to a hospital, where he was pronounced dead.

The drowning is being investigated by the King County Sheriff’s Office Marine Unit.

This is the first drowning in the Snoqualmie River this year.

On May 22, 2011, John Sharrar, 29, also of Bothell, drowned after attempting to rescue his dog, who had been swept away near Fall City. His girlfriend, Lidnsay Grennan, was saved due to heroic action by emergency responders from Snoqualmie.
