How do you know when you've found rapidly flowing water ?

[Kolyenka]

As the title says. I've found a spot that seems like it could be rapidly flowing water, but water doesn't show block information so I'm not sure how to tell. Is there any way to know ? Or do you just have to try building a water wheel there ?

I go by the sound, it’s loud. Functionally it does not spread out the way regular water does.

Like @BurgerDaddy said, rapids don't spread as far as normal running water, and are also very loud in comparison. They also tend to have a slightly brighter, more opaque coloring and produce a lot more water particles. 

I'm not 100% sure, but I think the game is also supposed to notify players if there are no valid rapids nearby when the player tries to place a waterwheel. That way the player has a better chance to catch their mistake before sinking the resources into the water wheel and then figuring out it doesn't work.
