Two days before the waters of the Guadalupe River swelled into a deadly and devastating Fourth of July flood in Kerr County, Texas, engineers with a California-based company called Rainmaker took off in an airplane about 100 miles away and dispersed 70 grams of silver iodide into a cloud.

Eight-year-old girls at sleep-away camp, families crammed into recreational vehicles, local residents traveling to or from work. These are some of the victims.

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.

New flood warnings have been issued along the Guadalupe River in Texas less than two weeks after flooding killed more than 100 people.

Kerrville's city manager met with the deputy head of mission from the Czech Republic's U.S. embassy Saturday at the local emergency operations center.

From jewelry to a heart-shaped summer camp sign, these are some of the objects found in the wake of this month's devastating floods.

Plans to develop a flood monitoring system in the Texas county hit hardest by deadly floods were scheduled to begin only a few weeks later.

At least 135 people died in the flood, the Texas Tribune reported. Among the dead were campers and counselors at Camp Mystic, a Christian girls summer camp on the Guadalupe River who were lost when a torrent of rain thrashed the region before sunrise.

This map shows where camps along the Guadalupe River were impacted by the July 4 flood. Meteorologists Pat Cavlin and Kim Castro detail how it all happened.

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.

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