While updating I realized I never officially released this mod, so...

TR Water Sound

http://morrowind.nexusmods.com/mods/42145/ required

Replaces most TR static water meshes with activators emulating water splashing sounds.

Pros: works with Dongle's meshes without needing special redone lava-like collision meshes,
it is easy to update if needed replacing TR_water_XXX statics with TR_water_XXXA activators.
Cons: may eat 1 FPS, there may be rare misplaced water sounds.

Anyway, enjoy and feel free to use as you like

I don't think I'll use this right now since I'm scraping for every FPS I can on my laptop. But this is another feat of brilliance, abot. I'm hoping that OpenMW's CS will give us water blocks/spheres/tables/etc by default.
