A weekend deluge in Texas caused catastrophic flash flooding that has killed at least 89 people, with the numbers expected to rise. Following a long Fourth of July weekend which should have been full of joy and fun, Texans are assessing the damage and searching for those who are lost.

It took just 90 minutes for the river to rise more than 30 feet. A look at the historic flood levels now etched into Central Texas history.

At least 47 people are dead in central Texas in what officials called a "mass casualty event" after devastating flash floods slammed Hill Country, with water rescues taking place along the Guadalupe River.

The death toll from the destructive Texas flash floods rose to 51 Saturday, with hundreds of rescuers combing through water and debris to find missing people, including children from a summer camp. The majority of fatalities were recorded along Guadalupe River basin in Kerr County.
