From July 13 to July 17, an intense and damaging rainfall hit the Hill Country region, affecting an area of about 1,800 square miles. This deluge poured down anywhere from 15 to 27 inches, leading to significant consequences for both the environment and local communities.
To put this into perspective, the total volume of water that fell during this period is estimated to be around 480 billion gallons! This staggering amount is enough to fill a standard 40-gallon bathtub a whopping 12 billion times—a truly mind-boggling figure.
Such an immense quantity of rain led to dramatic rises in the Frio, Sabinal, Nueces, Guadalupe, and Pedernales Rivers, which surged to dangerously high levels. Additionally, local creeks and streams, including Cibolo Creek and Hondo Creek, also experienced significant increases in water levels.
