This is the dramatic moment a helicopter crew rescued a resident stranded on a rooftop during the deadly Texas floods.

Footage shows the US Coast Guard aircraft hoisting the trapped local on a rescue basket as the deluge swamped his home in Kerr County, on July 4.

The Coast Guard said: 'An MH-65 Dolphin helicopter aircrew and an HC-144 Ocean Sentry Aircraft aircrew was launched from Air Station Corpus Christi along with an Air Station Houston MH-65 Dolphin helicopter aircrew to provide assistance with rescue operations.

'The Coast Guard has conducted 12 flights to the affected area, and rescued 15 campers from Camp Mystic in Hunt, Texas, yesterday. A Coast Guard rescue swimmer remained with victims of the flooding, providing medical assistance to and aiding with the evacuation efforts of 230 victims into assisting agencies air assets.

'Additionally, today, three people were rescued, and four were assisted from a mobile home community in Leander, Texas.'

Captain Ulysses Mullins, Coast Guard Heartland District Chief of Staff said: 'The preservation of life during this incident is our top priority which is why the Coast Guard is working with the State of Texas alongside other responding agencies to ensure that every asset on scene is able to coordinate, communicate and respond as safety and quickly as possible.'

Authorities said at least 82 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: '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.
