This included businesses and even a day care facility.  Personnel from Texas Military Forces were mobilized and sent into Marble Falls to help with rescues and evacuations.  The military personnel, along with swift water rescue and other first responders, completed 32 high water rescues and evacuated hundreds of residents.  Shelters were set up at the Marble Falls Middle School.

They waited with their two dogs on the roof in the dark for 2 hours, then were able to climb down and take shelter in a barn as the water receded slightly.  They waited for an additional 12 hours until they were finally rescued by boat.
