Catastrophic floods struck Central Texas over the July 4 holiday weekend, killing at least 129 people, including at least 36 children. Officials said more than 170 people were unaccounted for.

Thousands of rescuers continued to search for victims with federal and state teams assisting. But hopes for finding more of the missing had faded as search efforts reached a ninth day. Nevertheless, officials said they would continue searching until every victim was found.

Here’s what we know about the floods.

Most of the deaths were in Kerr County.

As of Saturday morning, at least 129 people had been killed in the catastrophic deluge. A majority were in Kerr County, a part of the Texas Hill Country northwest of San Antonio. The death toll in the county rose to 103 — 67 adults and 36 children — on Saturday, and officials reported 161 people still missing.

In other areas, at least nine people have died in Travis County, five in Burnet County, eight in Kendall County, three in Williamson County and one in Tom Green County, as of Saturday morning.

The dead included several girls as young as 8 who had been at Camp Mystic, a summer camp on the banks of the Guadalupe River with more than 750 attendees; 27 campers and staff members were reported dead there. Dick Eastland, the camp’s longtime director, was among those killed.

Many of the cabins at the camp were in designated flood zones, and some in areas deemed “extremely hazardous.”
