The grim task of searching for the scores of people missing from the devastating flood that struck Texas Hill Country nearly a week ago is taking an agonizing toll on searchers.

Follow along for developments on the July Fourth floods along the Guadalupe River in Kerr County and Central Texas.

Thousands of first responders and volunteers are working tirelessly to recover victims of the deadly Texas Hill Country flooding.

Since 2016, the topic of a "flood warning system" for Kerr County has come up at 20 different county commissioners' meetings, according to minutes. The idea for a system was first introduced by Kerr County Commissioner Thomas Moser and Emergency Management Coordinator Dub Thomas in March 2016.

Miriam "Holly" Frizzell of Abilene was remembered for her vibrant life and love of the normally tranquil Guadalupe River.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.

This isn't the first time flooding along the Guadalupe River has claimed lives. Jim Moore was a reporter who covered an eerily similar flood nearly four decades ago.

Recordings provided to CBS News showed first responders asking for an emergency alert to be sent, but dispatchers delayed because they needed special authorization.

Texas authorities said Tuesday 87 people died in Kerr County as a result of catastrophic flooding along the Guadalupe River on the Fourth of July. Five girls and a counselor from Camp Mystic remain missing, the officials said.
