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.

Kerr County remains at the center of the disaster after the Guadalupe River burst its banks on Friday. Ninety-six people in the county are dead, including 36 children, officials said Thursday. At least 161 others were still missing in the county.

Rain rushing to the Guadalupe took it from a depth of less than 8 feet to 37.5 feet, a deluge with as much volume as an aircraft carrier over five minutes.

As the Guadalupe River swelled from a wall of water heading downstream, sirens blared over the tiny river community of Comfort — a last-ditch warning to get out for those who had missed cellphone alerts and firefighters going street-to-street telling people to get out.

Newly released satellite images reveal catastrophic damage caused by the Hill Country floods along the 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.

In the days after the devastating flood that killed dozens in Central Texas, local officials have deflected direct questions about preparations and warnings in advance of the storm that struck July Fourth.
