We have chara growing all the way across the bottom of our pond, mostly in deeper water. One of the interesting things is that in a some of the areas that we have previously treated for the milfoil the chara is actually choking the milfoil and coontail back and taking it's place. I consider this a good thing since it does not grow to the surface like the milfoil and coontail does.

Right now it looks like we will be treating for just the milfoil and the coontail this year with "navigate" again, we are planning to leave the chara alone.
