The Dungeon Journal only reflects Normal and Heroic abilities, and does not have a separate section for any added mechanics on Challenge mode. Consider that part of the challenge, as it were. :)
In the case of Befouled Waters, you may want to take a look at the buffs visible on the boss during the fight, as well as the combat log tooltip of the effect that is killing you, for a hint.
