Transcript for Volunteers answer Harvey victims' pleas for rescue
The magnitude of the flooding is so hard to grasp. Right now up to 30% of Harris county, more than 1700 square miles underwater. That's equivalent to all of new York cy and Chicago combined. ABC's Eva pilgrim is right in the middle of the floodwaters. Good morning, Eva. Reporter: Good morning, George. This neighborhood covered by water. Can you see that car floating behind me. The homes empty. The people who lived here forced to leave. Before dawn we take off with a group of volunteers on a rescue mission. We got 4:00 just help. Reporter: Right away. Where are they at. Reporter: We hear calls from help from a stranded family. Hi, buddy. Y'all hang tight. Reporter: You okay? I'm scared. Was it flooded here yesterday. Yes. It's been flooded. Reporter: The relentless rain pouring into hopes that had been dry now leaving people trapped. We weren't aware that this area over here was this bad. We kind of went in blind this morning and you know luckily were able to find a lot of people. How many are in there. Two there and one there. Reporter: This group flagging down a police officer who set up a command center before putting out an sos on Facebook to their friends who quickly turned up with more boats. Just everybody come together and help each other out. Reporter: For hours they scour this area going from one home to the next carrying people they've never met before out on their backs. How do you know where to take them? You just take them to dry land. Reporter: The guys getting family after family taking them to safety. Come here, honey. We're a little different down here in the republic of Texas. We look out for each other and take care of our own. Reporter: And the coast guard estimates those guys rescued about 300 people. A lot of those volunteers telling me they're just fishermen with big trucks and boats. We have some of them here with us but no question these guys have been heroes throughout this. Amy. Yeah, they have big hearts as well. Thank you so much, Eva.
