Go to the north end of Grindstone late in the ice season and you’ll find them. They can get big, over a foot for sure; I’ve caught them on crappie minnows out there. They are by far the worst fighting fish ever, but a good way to get fresh smelt for bait.
We used to do this quite often in the late season on Grindstone, right before the ice went out. It was kind of fun, sort of a form of deep water panfishing and doubles were common.
We used waxworms or just something small and flashy, they were not difficult to catch, the hardest part was waiting for a light line rig to get back down as sometimes we were in 50+ feet. I recall that some of the other guys would use what they called a “depth charge”, a larger piece of shot 10+ feet up on the line to get the rig down quicker, but not so close that the fish felt the extra weight before they were on.
Smelt were the only fish that I can remember being able to actually see bite on the primitive electronics of the 1980s. Even on the old school LCD graphs, you could clearly see the line and then a cloud would “rise” from the depths. It was pretty amazing back in the day.
My father knew several older Norwegian guys who were too old to fish, but that loved smelt 20 ways from Sunday. Salted, smoked, pickled, canned, fried, dried, cured, etc, so we used to fish. We used to prep the fish and give them away and the old guys would have days of entertainment storing them away and eating them.
