For the same reason that clouds appear to be white.
The water droplets in the high speed water as they form a spray and as they are agitated are all different sizes, and so reflect the wavelengths of all colors, which when combined then appear to us to be white.

Your mental picture of water flowing at high speeds is probably from something like the Colorado river, or a waterfall. As other answerer said, it is air bubbles in the water, which happen from the agitation of the water and its exposure to the surrounding air. (Think about waves at the beach. What happens when the waves crash on the beach - they get frothy, for the same reason as above.)

I go white when I travel at high speed too.

Yes you are right.
But if the water travels at high velocity in open channels then it will look white due to air ingress into water and formation of foam.
At higher velocities the Reynolds number will be high and it dissolve more air, due to high Reynolds number the stream will be turbulent and due to air presence foam formation will be more and it looks white.
I hope I answered your question.
