Who paid them to seed the clouds?! Rainmaker CEO Augustus Doricko confirmed cloud seeding occurred in the Hill Country two days before severe floods, but claims it had no role in the disaster. He said only two clouds were seeded and effects would’ve faded in hours. Experts note it’s hard to predict seeding impact, with rainfall increases ranging from 0% to 20%. The Guadalupe River at Kerrville rose 26 feet in under an hour during the flood.
