The search for survivors in the wake of catastrophic and historic flooding in Texas has entered its fifth day as the death toll surpasses 100 with dozens of people still missing.

A search for Texas flood survivors intensified as Texas Governor Greg Abbott issued a disaster declaration for nearly two dozen Texas counties.

At Camp Mystic, a Christian summer camp in Hunt, Texas, where officials are grieving the loss of 27 children and counselors, belongings of the young campers were strewn about the flooded floors of a dormitory, while other items, including a pink backpack and a Camp Mystic T-shirt, were found along the bloated Guadalupe River, photos show.

More than an entire summer's worth of rain fell in some spots in just a few hours, quickly overwhelmed dry soils and created significant flash flooding.
