The Texas Hill Country has been notorious for flash floods caused by the Guadalupe River. Here's why the area is called "Flash Flood Alley."

The search for victims along the Guadalupe River has become a grueling, painstaking slog. Several thousand volunteers from across the country are helping.

Julia Hatfield, a songwriter who survived the July 4 floods by fleeing her RV park, says more help is needed in Kerrville.

Volunteers and rescue crews are still searching for the over 100 people that are still missing from the floods that killed at least 135 people.

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.

In what experts call "Flash Flood Alley," the terrain reacts quickly to rainfall steep slopes, rocky ground, and narrow riverbeds leave little time for warning.

A washed-out Guadalupe River appeared stuck in time nearly two weeks after the catastrophe. Large trees laid on their sides and remnants of debris lingered throughout what was left. Some residents of the area say it's unlike anything they've seen in the river before.

Camp Mystic is grieving the loss of 27 campers and counselors following the catastrophic flooding in the Texas Hill Country.

A flood watch is issued when conditions are favorable for flooding, according to the National Weather Service. It doesn't guarantee flooding will occur, but it means flooding is possible. Areas north of Dallas to the Red River will remain under flood watch until 7 a.m., according to the NWS in Fort Worth.

The dammed reservoirs along the Guadalupe River near Kerrville are believed to have captured debris washed downstream.

Hill Country residents and volunteers are racing to return lost belongings to victims of the Guadalupe River flooding. The big picture: Dondi Voigt Persyn of Boerne leads a Facebook-powered grassroots effort returning everyday items that may now mean everything to flood-affected families.
