Hundreds of 911 calls from the devastating July 4 floods in Texas that killed scores of young girls at storied Camp Mystic have been released — and they paint a horrifying, tragic picture of victims’ final minutes.

Some of the frantic calls included the sound of children screaming in the background as shaking voices pleaded for rescue.

Others captured doomed rescue workers in their final moments.

“The tree I’m in is starting to lean, and it’s going to fall. Is there a helicopter close?” said desperate firefighter Bradly Perry in a call with dispatchers. “I’ve probably got maybe 5 minutes left.”

Those 5 minutes would pass without a chopper arriving, and Perry soon became among the 137 people who died across the state.

The calls were among more than 400 emergency recordings released by Kerr County and Texas officials Friday.

Just two dispatchers were working in the early hours of the holiday morning when the floodwaters began to rise, and they raced to help people as quickly as they could before being forced to hang up and move on to the next caller, the audio shows.

Some of the chilling calls to the dispatchers capture the chaos that unfolded in and around Camp Mystic, a Christian girls summer retreat for the children of the state’s political elite that suffered 27 deaths from the flash floods.

“There is water everywhere, we cannot move. We are upstairs in a room, and the water is rising,” a frightened woman from the camp said in a call.

Camp Mystic lost 25 of its campers and three staffers in the July 4 flood, which killed at least 137 across Texas.

“How do we get to the roof if the water is so high?“ she said in a later call when help still hadn’t arrived. “Can you already send someone here? With the boats?”

But the overwhelmed dispatcher couldn’t help her.

“I don’t know, I don’t know,” the 911 operator said.

Another woman who lived downriver from the camp was audibly shaken when she called 911 to report that she’d rescued two campers who’d been washed away from Mystic.

“We’re OK, but we live a mile down the road from Camp Mystic, and we had two little girls come down the river. And we’ve gotten to them, but I’m not sure how many others are out there,” she said.

Twenty-five of Camp Mystic’s girls would be killed in the flood, along with three staffers.

Mystic — where former first lady Laura Bush was once a camp counselor — was just one of numerous camps and RV parks along the Guadalupe River that were washed away in the floods.

“There’s water filling up super fast, we can’t get out of our cabin,” a counselor from another camp said in a call where children could be heard screaming in the background. “We can’t get out of our cabin, so how do we get to the boats?”

The dangerous pace of the flooding was also made apparent by the calls.

Numerous people called dispatchers several times to give updates about where they’d ended up — with families moving from ground levels to second floors to attics and finally to roofs all within just 30 to 40 minutes.

Dispatchers often had just moments to help callers before having to move on.

In some instances tragedy, would befall callers while they were on the line, including an incident where a woman was relaying information to an elderly friend who was flooded in his home up to his head — till the man then stopped responding after his phone cut out.
