Rescuers used boats and jet skis to help evacuate residents of about 50 homes in a subdivision near Lake Granbury last night as Robinson Creek spilled out of its banks.
Bands of heavy rains have been parked over portions of Texas for days, creating flooding situations along creeks and rivers.
Hood County Judge Andy Rash says some of the people at Lake Granbury waited on the roofs of their homes. The water was waist to chest deep. No injuries were reported.
Rash said Robinson Creek, which flows into Lake Granbury, was continuing to rise late last night.
Pastor Neil Norman says about 30 people were taking shelter this morning at the First United Methodist Church in Granbury.
Meanwhile, a 13-year-old boy died in the Dallas suburb of Garland after being washed down a flooded creek.
Police spokesman Joe Harn says the boy, identified as William Griffin, was swept away when firefighters tried to pull him ashore from a bridge pillar where he was stranded.
He was found a mile downstream about two hours later and pronounced dead late last night at a hospital.
