This is the dramatic moment a boat dock with vessels still attached floated away during severe floods in Texas.

Footage captured by Ryan Schuring shows the entire platform drifting along the floodwaters on July 6.

Ryan said: 'The flooding in Central Texas is absolutely heartbreaking. This is near Lago Vista, Texas, outside of Austin.

'Entire boat docks with boats still attached floating down Lake Travis. Search and rescue underway for a missing fire marshal. Tragic on so many levels. Prayers needed.'

Authorities confirmed that more than 100 people were killed in the massive flooding that struck the region, including 28 campers who went missing at Camp Mystic in Kerr County.

Texas Governor Greg Abbott said in a press conference on Sunday: 'I had the opportunity yesterday to visit Camp Mystic to see firsthand what happened there. It was nothing short of horrific.

'We're here in Austin today because there have been lives lost in this greater region. We are broadening the area that we're focused on, but we are not reducing our focus in the Kerrville area.

'There are dangers over the next 24-48 hours that could pose public safety threats. If there's any water on the road, the most important thing you can do is to protect your lives. Remember: Turn Around, Don't Drown. Texas continues our 24/7 operations to search for anybody who was affected by these deadly storms.'

The Texas government said more than 1,500 personnel and 925 emergency vehicles have been deployed for search and rescue efforts.
