Authorities are investigating a fatal incident at Steamboat Lake State Park after a Steamboat Springs man was found dead in the water on Saturday afternoon, according to a statement from Colorado Parks and Wildlife.

Park rangers responded around 3 p.m. on May 3 to a report of an overturned watercraft and located a U-shaped inflatable fishing tube, known as a “bellyboat,” floating upside down. No other people were seen nearby. 

Further search led rangers to a person below the surface of the water, still attached to the float tube by a safety strap. The individual was removed from the lake and pronounced dead at the scene. Officials noted that the person was not wearing a life jacket.

The victim later was identified as Gregory Bjorgum, 72, of Steamboat Springs. According to Routt County Deputy Coroner Jacob Custer, official cause of death will be determined once an autopsy has been performed. 

According to witness accounts, the incident occurred near the Rainbow Ridge day-use area, where Bjorgum was seen fishing. Weather reports indicated high, steady winds at the time of the incident. The investigation is ongoing.

Park officials are reminding the public to be cautious on the water, especially in spring, when water temperatures remain cold despite warmer air. They recommend always wearing a personal flotation device during water activities.
