It's only absurd because you went online, found a couple pictures of rivers found in deserts, and lacking any experience, extrapolated them to every other stream in every desert. I'm not sure which part of your statement was more wrong, but if you had any practical experience you'd know that the majority of the desert streams are shaded in part or in whole from high noon sun. You may also be aware that flowing systems can react in VERY peculiar ways such that your guess at how temperatures will respond is pretty nearly worthless. I camped by a streambed that became a flowing stream right around dusk, but was totally dry the rest of the day. When do you suppose the maximum temperature of that stream was? Broad generalizations are kind of hard to make, but you can pretty much say that water will be warmer later than noon. Flowing streams may reach a peak heat much later than the air...or not.


Although you are concerned with the survival of non desert species in the desert like the redband I am not as that is not game that I can win as Dan Schill pointed out in the video I posted re the redband trout. The issue I focused on was that the majority of native desert fish are extinct or endangered and therefore endangered native species of desert fish should be reintroduced as a much more realistic and viable solution.
Reintroduced to what? They weren't there in the first place, so if you introduced them they wouldn't be native...by definition. The redbands ARE native.
B.t.w Dan is right the redband does look like a species of rainbow trout.
Rainbow Trout:
Oh good. Then all the genetic samples we've taken over the last few decades don't lie.

Astonishingly I had to argue quite a lot to establish humans as the dominant animal on the planet. Mako sharks are still, in my view, the topmost pelagic predator, and from memory you agreed at the time.
I never agreed or even came close to agreeing. The evidence ALL pointed to the fact that you were wrong, and it does so even more today.
