An urgent alert was issued, and a Coast Guard helicopter and 45-foot response boat were deployed to search for the missing boat, the release said. After arriving at the search area, the Coast Guard boat crew spotted a flare burning in the distance - it was the missing vessel, officials say.

The team deployed around 7 a.m. Friday from Corpus Christi, about 200 miles south of where the Guadalupe River in Kerr County, Texas, had risen from about 3 feet to nearly 30 feet. Floodwaters in the area had swept through and battered several youth camps on the river banks — including Camp Mystic, the summer camp where they were headed.

Coast Guard Petty Officer Scott Ruskan rescued over 200 people during his first mission over the weekend from floods that killed over 100 people.
