But aren't water hyacinths one of those species that can be a real invasiveness problem? The right balance of koi and plants could work out great. Maybe your koi weren't big enough last time, or hadn't figured it out. I don't think koi are terribly bright sometimes. Here is our biggest one, just being returned to the pond (it's all muddy and filling now) and it spent a good few seconds trying to swim back up on shore, duh!
