KERRVILLE, Texas (AP) — Over the last decade, an array of Texas state and local agencies missed opportunities to fund a flood warning system intended to avert a disaster like the one that killed dozens of young campers and scores of others in Kerr County on the Fourth of July.

Key questions remain unanswered about the actions Texas officials took both before and during the catastrophic July Fourth holiday floods as a painstaking search for victims continues along the Guadalupe River nearly a week later.

Kerr County, Texas, lacked a “last mile” warning mechanism that could have saved residents before the deadly floods devastated the area, including a children’s summer camp, killing more than 80 people.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

Lt. Gov. Dan Patrick told CBS News Monday that the state of Texas could pay for storm sirens along the Guadalupe River.

Hope of finding survivors of the catastrophic flooding in Texas is dimming a day after the death toll surpassed 100.
