> I'm not sure those are meant to be tagged, a pool is inherently unroutable since it's a body of water, and I don't know of a standardized tagging for "suggested paths through water". 

I might have been unclear, I'm not trying to suggest paths through the water, but rather, that is the direction of active water flow/current (as a result of the water slides), although those are also the paths exiting the water slide current (either out of the pool area or into the lazy river, which I marked according to current flow).

> No, the wiki should only be changed if there's a large usage of the tag

I wasn't meaning that the wiki should be changed, rather asking if I should change the tag on the object. Anyway, I did change the tag, from highway=lazy_river to leisure=lazy_river
