All,
Strolling through the forum today and saw this thread, thought I'd add my two cents.
Be very careful using herbicides around water. Make sure they are labeled for use in or around water and that you stay within the bounds of the label.
Of course, I'm in the fisheries management and pond management business and if a commercial applicator doesn't follow labels, there are serious fines, not to mention it's just not healthy for water.
