A small armada of boat owners from all across the United States have descended upon Texas. Known as the 'Cajun Navy', they have saved lives and taken the heat off overwhelmed rescue forces.

Todd Terrell, a team leader for one of the groups told the LA Times that his group had mobilized 763 boats and more than 1,500 volunteers operating in different parts of Texas.

“There are people who haven’t had food or water for three and four days,” he said. “Right now, some of the water is so bad and so high, we’re bringing them supplies until we can pick them up tomorrow. It's so widespread, we are just trying to stabilize everybody and rescue tomorrow."
