Yeah, I think the combo of lots of clay + the right geographical channeling for flash floods is somewhat rarer, so you get what you describe, random sudden rivers and brand-new lakes, and not flash floods as often.

In the desert, a dry creek bed is the most dangerous place to sleep or even hike, because a sudden thunderstorm can fill it in literally minutes— or rather, the thunderstorm has been filling it upstream from you for an hour, and when it gets to you, the water will rise in minutes— as in the example from Australia I posted above.
