SPOKANE, Wash. -

Fire crews a pulled a man out of the Spokane River near People's Park Saturday afternoon.

According to Assistant Fire Chief Brian Shaeffer, around 1 p.m., two men were rafting when they somehow fell off their inflatable devices.

One of the men was able to get to safety, but the other became trapped underwater. Firefighters said he was tangled in a grate at the bottom of a pillar of the Sandifur Foot Bridge.

"What's an incredibly frustrating problem for everyone here, including the rescuers, is being able to see the person underwater, and every tool we tried (wasn't) effective in removing him from the grate," said Schaeffer.

They were able to free him around 2 p.m. They attempted to resuscitate him, but he was transported to Deaconess Medical Center where he was pronounced dead.

Schaeffer said there are ways to make sure you're safe if you hop the water.

"Scout it out, wear your PFD, make sure water craft is an approved water craft, make sure you travel in twos and make sure someone always knows where you are. It's incredibly important. Things like this can happen in seconds and be life-altering."

The Spokane Police Department is investigating the incident.
