When you catch one of those original smallies try to get a picture of it so others can see what a fishery like yours produces. Carlender indicates those originally stocked smallies should live 15-18 years. Keep in mind they could become harder to catch as they get old and more conditioned to angler's baits. Please keep us advised as to their progress with pictures or body measurements in this thread. If those bass only gain 1/2 pound a year they could weigh 8-9 pounds near the end of their life. The Indiana state record angler smallmouth was 7 lb 4 oz. Current conditions of your pond are ideal for growing trophy smallies. I put this thread in the archives under the SMB Discussions - Northern Ponds topic.
More Reading Material - Here is a link to a good discussion about amount of forage needed to produce high quality and/or trophy fish:
http://forums.pondboss.com/ubbthreads.php?ubb=showflat&Number=369585#Post369585 The pond of RAH as decsribed appears to be on the path to growing big smallmouth bass: few predators and numerous appropriate sized forage fish - a high ratio of Forage to Predator. Keep in mind that RAH does not feed pellets to his fish so the forage:predator should be a high ratio when the goal is trophy sizes.
