That sounds familiar. I guess those are the 2 biggest problem weeds in our area. I've seen ponds just about choked out with them. My pond is new, with not a single weed so far. If I see a single alligator weed or WP, I'll try to nip them in the bud.

I honestly don't think a heavy infestation can be defeated by mechanical means. I think it would take chemicals.
