A 2-year-old girl has died after she fell into a septic tank at a Texas RV park — drowning as rescuers scrambled to save her, according to officials and reports.

Little Charleigh Nicole Nelson was walking on the lid of the wastewater tank at Paradise Lagoons RV Resort in Aransas Pass Wednesday when she plunged nearly 15 feet, according to KRIS-TV.

Her horrified family tried to rescue the girl with rope and shovels to no avail — as cops and firefighters raced to the scene, the local station reported.

Rescuers clambered to pull the child out through a 2-foot-wide hole in the tank — which was filled with 3 nearly feet of water — at around 5:30 p.m., the Rockport Volunteer Fire Department said in a press release.

They removed the child’s lifeless body from the tank after about an hour.

“This is a terrible tragedy for the family of this child, her neighbors who witnessed the event, and all of the 1st responders who assisted in the recovery,” the press release states.

The child’s heartbroken mother Brittney Nelson said she was in “disbelief” after the fatal fall.

“We are clinging to each other tonight…Please, please keep praying,” she wrote on Facebook. “Pray for our family members that are traveling to us as well. I love each and every person who has messaged us. We are definitely going to need yall.”

It wasn’t immediately clear Friday how the child fell into the septic tank but park residents told KRIS-TV the girl that the lid of the tank buckled underneath her.
