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.

Many camps in the Guadalupe river region are adjacent or are partially inside high-risk flood zones, according to maps from the Federal Emergency Management Agency.

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.
