The application RAW Power tells me the red channel clips in the river, but the other channels do not.

The JPEGs you included tell a different story. In the OOC JPEG, the red and green channels are both blown in yellow areas of the flow. In the reddish areas the green channel isn't blown but the red channel is blown or close to blown. The blue channel is generally not blown at all in the flowing lava but it's blown in the white erupting part. (You get white when all three channels are blown).

In the version you edited the big problem is that the blue channel is mostly blown as well as the red and green channels in the flowing lava. The difference is quite clearly illustrated by looking at the blue channel only:

Yes. We are getting our wires crossed a little bit, and it's partly my fault. Neither of these are edited. The second is a screenshot of a preview of the raw file, showing how it displays (blown out) on my screen. The actual raw file is here (sorry, I didn't post it earlier)

The raw file says only red clips, yet it displays as white, until I switch those switches. This appears to be because of the way the gamut is mapped to my screen.

Finally, I've found your RAW, and I decided to cook it.

Fist is your raw cooked in SilyPix with initial settings, which means that I did not move any sliders

Second is product from ON1 RAW developer with initial settings, just to compare results from 2 different programs under initial settings.

and 3d photo is the result of my intervention in ON1 development with 2 touches only:  first is AI tone adjustment, second is AI NoNoise which I apply to all RAW shots.

and conclusion is up to you.
