Colette Sulcer, 41, and her child - who has not been identified - were driving in their hometown of Beaumont when their vehicle got stuck in high water from Hurricane Harvey.
The police and rescuers pulled the baby and the woman onto the boat and attempted to resuscitate the mother, to no avail, according to AP.
When Sulcer and her daughter exited the vehicle, they were swept a half mile away from the auto.
The current carried the pair into a waterlogged canal. She was found around a half mile from her vehicle.
The mother was seen trying to save her 18-month-old from a flooded parking lot when they were swept away into a ditch, a Beaumont fire-rescue official said. Beaumont Police reported that the child would have died had they went under the trestle, as the divers wouldn't have been able to reach her.More news: Trump Bans Transgender Recruits from the Military
"Everyone in the hospital fell in love with her", Officer Carol Riley, a spokeswoman for the department, told People magazine.
'The baby also had a backpack that was helping her float on her back and she was holding on to her mom, ' she added.
The woman drowned in the water while the toddler survived.
Police said the toddler was alert but was suffering from hypothermia. First responders lifted the child from her mother's body and tried to revive the woman, but she never regained consciousness. She was later pronounced dead.
The child was taken to the Christus St. Elizabeth Hospital in Beaumont, and was expected to be released Wednesday.More news: South Korea: Kim Jong Un's third child born in February
"So we're thankful that the child was able to be rescued", she concluded.
Two firefighters and two police officers were among those who caught the Beaumont residents just before they were about to be swept under a railway trestle. He was reportedly out of town when tragedy struck.
The child lived but Sulcer died, police said.
Riley credited Sulcer with saving her daughter's life. Harvey has since weakened to a tropical storm. The death toll is expected to rise significantly once floodwaters recede in the coming days and weeks. The storm has now moved into southwest Louisiana, according to latest reports.More news: Destiny 2 PC Settings Detailed, Features 4K HDR, 60FPS
