BLITZER: Some good news for the 188,000 people forced flee their homes in Northern California fearing a three-story wall of water could be released from the country's tallest dam. The problem? A main spillway is backed up and damaged. Let's go to CNN's Paul Vercammen. He's on the scene for us. I know you have an update, Paul. Give us the very latest.</s>PAUL VERCAMMEN, CNN CORRESPONDENT: Well, we'll give you, we'll show you the very latest. Now, success on this story, this dramatic effort, to keep this dam from spilling over, bursting with the compromised spillways. It's measured in inches. And look behind me, Wolf. If you see off in the distance, that is the water pouring out of Oroville Dam into the Feather River, kicking up all that spray. That's a good sign, because they say the water level here is now dropping at about four inches per hour. It had peaked, of course. It was going over the spillway, and that's when all these fears for massive flooding and possibly a huge and colossal breach surfaced. That's when they evacuated all those people. If we come back over here, this is Oroville Lake, and look at it. We can give you an interesting perspective. During the drought, more than two years ago, you could walk parts of this lake. You could walk the lake bed, Wolf, and now it's completely filled with water. They have had so much rain here over the past few months. The good news as we pointed out, the lake level is dropping. They needed to drop even more before the next storm hits so they could assure everyone's safety. Back to you now, Wolf.</s>BLITZER: We'll take the good news for now. Paul Vercammen, thanks very much. Right now the president and the Canadian Prime Minister Justin Trudeau, they're having lunch ahead of their joint news conference scheduled for the top of the hour. Looking at live pictures from the East Room of the White House. When we come back, my panel will weigh in on how these two very different world leaders will try to narrow their difference on key issues, including trade and immigration. Stay with us.
