Denise, Ian, we're on week five of an epic journey on the Colorado River from its beginning all the way to the end.

And now we find the two of you out in the desert part of Southern California near the towns of Hopeville and Brawley.

I've been out there.

It's out there.

That's right, Gustavo.

It's about a three-hour drive from L.A., and that's without traffic.

It's as part of California known as the Imperial Valley, which stretches over Southern California,

bordering Arizona and Mexico. At a basic level, it can just be difficult working outdoors

there because it gets so darn hot. Oh my God.

It got up to 110 degrees.

And it is the desert, but this one part of the desert is especially rich in water.

And it's just miles and miles of farmland.

And of course, miles and miles of canals that irrigate much of the nation's winter vegetables.

All types of crops, lettuce, broccoli, carrots, spinach, alfalfa, and other types of hay for cattle,

all kinds of things.

Oh my god, how could food even grow there without getting toasted?

Well, the winters are ideal for growing vegetables in the desert.

Crazy, right?

Yeah.

And other crops like hay grow in the summer.

And so even though we are talking about a desert, it does get the largest share of the Colorado River water.

Why, though, would a desert get the largest share of the Colorado River water.
