The rain that fell from July 13 to July 17 was truly devastating.

In an 1,800-square mile stretch of the Hill Country — from Hondo through Uvalde, up toward Camp Wood and Utopia — anywhere between 15″ and 27″ of rain fell.

If you convert that to volume of water, the amount balloons to an estimated to 480,000,000,000 gallons — a staggering amount that could fill a 40-gallon bathtub 12,000,000,000 times.

This massive volume of water resulted in destructive rises in the Frio, Sabinal, Nueces, Guadalupe and Pedernales Rivers.

Cibolo Creek, Hondo Creek and other local creeks and streams rose to dangerous levels, as well.
