You might consider some of the bloodlines (Unearthed Arcana) that gain water breathing at higher levels, such as the black, bronze, gold, and green dragon bloodlines (L20) and the storm giant (L20).
There are also certain prestige classes that might work to your advantage, like the Elemental Savant, which transforms a being into an elemental al L10.
You might also look at certain templates, like the half-dragon for Oriental Adventures dragons, some of which have water breathing.
