Here (with rain falling in front of the lens) are the Cascades. If you've been there, especially during flooding, you know it's basically impossible to get a photo that represents how impressive they are. They're in full spate now.
And this is the source of the flooding. This culvert goes under Cataract Street. As you can see, at 8:30am, it was full. By 9, it had overflowed the basin, run across Cataract, and down the hill. By 10, the Lodge driveway was gone.
