Versatility of non-ice water college spells

[Tenrath]

Background: I have a TL3 D&D ranger-like character who has one-college magery in the water college. The campaign is fairly split between combat and social interactions, with a little less survival. Power level around 300cp. Thematically, the character avoids freezing water and instead uses the water or acid spells in the college.

My question is; what fun uses do you all have for the water college spells that do not involve ice or freezing?

I'm interested in any use cases (combat, social, or survival) where these spells have come in handy or added a fun element to the game.

Thank you!
