The driest places tend to have the most tightly-regulated water.

And the wettest places tend to have the least-regulated water.

(Nobody talks about it because shortages make bigger headlines than surpluses do, but there's a ton of agricultural areas in the US that have too much water and where providing drainage for farm fields is much more commonplace than irrigating them is.

It doesn't really matter in this context, though, because folks hate datacenters in these water-rich areas just the same as they do everywhere else.)
