Hi Octal7 -
The basic way to do that is to create a mask to match your video. In PDR, you can make a brush mask so that colour changes only affect the river water...
BUT
That's fine if it's a static shot, with no panning or zooming. Obviously, the shoreline will shift as the camera pans/zooms so you need a mask that can track the shifting shore/river edge.
My first thought is that's more of a job for ColorDirector (motion tracking mask) but I'll try to get my brain into gear.
Cheers - Tony
