Rhett LarsonGUEST
So in the latter part of the 19th century, early 20th century, the United States had all of this undeveloped desert land, and they wanted to get a lot of people to move there.

Rhett LarsonGUEST
Well, a great way to get a lot of smart, hardworking people to move to the desert is to make it a race, and to tell people, "Run as fast as you can into the desert, and if you win the race, you get the most valuable resource you can own in the desert.

Rhett LarsonGUEST
So run to the water." So people ran, and the first people who grabbed the water- got superior priority to anybody who came after them.

Rhett LarsonGUEST
Well, that meant a lot of people were moving to California, and California started gobbling up the river.

Rhett LarsonGUEST
So all of the other basin states said, "Well, we don't want this rule to govern," so we negotiated the Colorado River Compact that basically split the river between the upper basin and the lower basin.

Mike BroomheadHOST
What were the laws? How did we get? Because I thought this was a fascinating explanation of how Arizona was settled and became a state and how they got people to come here.

Rhett LarsonGUEST
Most water law in much of the world in the Eastern United States is governed by who owns land next to the river.

Rhett LarsonGUEST
But that didn't make a lot of sense for the Western United States because a lot of the people who were moving out here in the 19th century wanted to mine.

Rhett LarsonGUEST
Additionally, the federal government had all of this desert land and they wanted to get people to move there and settle it.

Rhett LarsonGUEST
Well, a great way to get a bunch of hardworking people to move to and invest in a desert is to turn it into a race and promise people if you run as fast as you can into the middle of the desert and grab the water, you'll own the most valuable resource you can possibly own in the desert.

Mike BroomheadHOST
Does that add to the fear factor with data centers and some of these others? Is there a reality in that fear? Or do you think that the data centers can actually be water neutral if they're forced to do it?

Rhett LarsonGUEST
I think the data center conversation is really interesting because a lot of the opposition to data centers has pushed that industry to be very water efficient.

Rhett LarsonGUEST
And so most of the data centers that are coming into Arizona don't use evaporative cooling.
