Toledo,
This weed amazed me by how fast is took over the ponds what once had chara. It was like one year there was chara. And then one or two years later there was no chara and tons of the naiad filling the pond and clogging up the surface. So I don't think it would take much if the conditions are right for establishment. I don't know where to buy it but I can guarantee some public ponds that are near you have it. Its growing now and already a nuisance in the pond I mentioned so I am sure you could find it this weekend nearby.
As for how to get it established, just move some being careful to select just the plant you want. You don't have to plant it or anything. It can grow even detached from soil. Where it contacts soil it will root and form tubers. Do not use water from the impoundment to transport it. Bring your own water. To be sure you don't transport critters, you may try dipping in a salt bath agitating it to remove them. Do it long enough to dislodge them but no so much as to kill your weed.
There is a critter you want in your duck pond. Hyallela Azteca. You can buy them from
