AUSTIN (KXAN) — On Friday afternoon, the Travis County Sheriff’s Office released the name of the diver who drowned in Lake Travis on Thursday, who, despite rescue efforts, did not resurface from the water.

According to TSCO, although Round Rock resident Sebastian Medina-Page, 38, was recovered by people in the area and CPR was conducted by ATCEMS medical professionals, rescue measures were too late and he was pronounced dead.

Investigators said Medina-Page — a project manager/diver — was working on a broken pump for a private residence at 700 Hurst Creek Road in Lakeway and somehow ran out air. 

Lake Travis Fire Rescue and the Austin-Travis County EMS said the rescuers tried to perform CPR and other life-saving measures for more than 30 minutes, but the diver did not survive. 

Fire officials said in that area of Lake Travis, the depth of the water can change quickly from 10 feet to 70 feet. 

At this time, officials aren’t saying what caused the air supply to drain.

Diving conditions on Lake Travis

KXAN spoke with a local certified scuba diver about the current diving conditions on Lake Travis.

Robert Weiss, owner of Lake Travis Scuba, said he recently went diving to inspect a pipe.

“The depth that I went down to is 70 feet,” he said. “As you come down, you get greener and greener water until it gets to be kind of brown, dark, and it gets to where you lose all the light.”

He said at about 10 feet, you will still get some natural light if you’re diving during the day, so your visibility will be about 10 feet.

As you go deeper, however, visibility diminishes.

Weiss also said while sediment is starting to settle, last year’s flooding worsened the visibility. 

“All that mud water, all that turned up water that was coming through the floodgates and through the floods came down and mucked up our lake,” he said. This time of year, Weiss said the water temperature is around 55 degrees.

“If you’re not properly dressed for that, you can get extremely cold,” he said. “If you’re not paying attention, by nature of being cold, you can be breathing more rapidly, using your air consumption, much greater.”

As you go deeper, you also use your faster, Weiss added. “At 33 feet, every breath takes two times the volume of air as we breathe up here. At 66 feet, it’s 3 times the amount of air.”
