You may not so much as be able to start a snail population with adult RES established. If there is a population, it'll be limited. Likely, if they can survive in your pond, they're already there.
A controlled snail population doesn't mean wantom disease and parasites will affect/infect swimmers, just slightly inceases the chances. Then there's the benefit of an additional food niche for your RES. As long as you have a healthy bunch of RES, snails have little chance of overpopulating.
Put some large RES in your aquarium and Presto, no more snails!
