Authorities have identified a 23-year-old Parker man who died Sunday tubing alone on the Arkansas River in Lake Pueblo State Park.

Steven Kelly was below the dam near the Cottonwood Picnic Area when he drowned, according to Colorado Parks and Wildlife, the Denver Post reports.

“It appears Kelly was trying to avoid drifting down the river by tying a rope to the footbridge located there,” CPW said in a Monday news release. “The rope was then tied to his inner tube and his ankle. The tube broke away in the swift water and Kelly was unable to detach himself from the rope before he drowned.”

Authorities say Kelly was discovered by park rangers about 11:30 a.m. “It is believed he was wearing a life jacket, but neither the tube or the life-jacket were recovered,” the release said.

Kelly is one of three confirmed and one presumed deaths on Colorado rivers over the weekend.
