CHERRY CREEK RESERVOIR, Colo. (KDVR) — A man went missing Saturday evening at Cherry Creek Reservoir.

South Metro Fire Rescue and park rangers responded to a call that was reported around 6:45 p.m. to search for a missing 29-year-old man.

A South Metro Fire Rescue spokesperson said the man was tubing behind a boat when he went under. He was not wearing a personal flotation device.

Rescue crews were unable to locate the missing man, and the rescue transitioned to a recovery operation after 90 minutes, the spokesperson said. The recovery operation was turned over to Colorado Parks and Wildlife’s Marine Evidence Recovery team.

Due to the continued search, the reservoir is closed to boating on Sunday. The rest of the park does remain open.

CPW’s MERT team utilized underwater remote-operated vehicles to search for the man until 4 a.m. on Sunday morning. CPW will continue its search at 10 a.m.

According to CPW, this drowning comes nearly one year to the day of another drowning at Cherry Creek State Park. A kayaker had flipped over and drowned near the East Shades parking area.
