First of all, you can't know wood jutsu, it's a keki genkai that only shodaime-sensei and yamato possess. Second of all, a low-level fireball jutsu wouldn't be able to affect the water, let alone evaporate it.
FIRST OF ALL, THAT IS ONLY BECAUSE NO ONE HAS EVER TRIED TO MIX THOSE THREE ELEMENTS TOGETHER SUCCESSSFULLY, NINDAIME DID NOT TRY BECAUSE HE TOOK OVER SHODAIME WHILE HE WAS ALIVE AND SO HIS JUTSU WAS NOT NEEDED
AND INSTEAD I USE Doton: RETSDOTENSHO: SPLIT EARTH TURNAROUND PALM
ERUPTS THE GROUND BENEATH YOU, RELEASING THE WATER ND TRAPPING YOU UNDERGROUND
Doton: Yomi Numa : Swamp Of The Underworld
Drowning You Underground
