A shivering toddler was been found clinging to her drowned mother after they were swept into a drainage canal by floodwaters in southeast Texas late Tuesday.

Colette Sulcer and her daughter were driving south through central Beaumont — a city some 75 miles northeast of Houston near the border with Louisiana — when their vehicle got stuck in high water, police said.

Sulcer, 41, of Beaumont, abandoned the car in a parking lot and tried to flee to safety with her daughter, Beaumont Police Department said in a statement on Facebook.

"At some point she was swept into the canal and ended up floating about ½ mile from her vehicle," a police spokesman said in a statement. "Two Beaumont Police Officers and two Beaumont Fire Rescue divers in a Zodiac boat, spotted the mother floating with the small child. The child was holding on to her mother."

They plucked the pair from the water moments before the two slipped under a floating railroad trestle.

"Water was up to the trestle and first responders would not have been able to save the child if they had floated under it," the spokesman said. "The mother was unresponsive. The child was responsive but suffering from hypothermia."

They tried to revive Sulcer but she never regained consciousness. The child was in a stable condition.

While police did not say how old the girl is, the Associated Press reported she was 18-months-old.
