Welcome to the forum FF. I live in SF now but lived in Vermillion for many years. First of all the ice doesn;t seem to usually be that great down there. This year seems to be an exception to the last few years. I have fished ice on Lewis and Clark, the marina by the dam, Lake Yankton, Marindahl (south of Irene), otherwise I would have to drive north a ways to fish Brandt, Madison, Thompson, ect. Sometimes you can catch walleyes on Lewis and Clark, crappies and bass in the marina, crappies, bass, perch in Lake Yankton, bluegills and crappies in Marindahl. Starting out I would head to Lake Yankton or Marindahl for panfish with some waxworm, maggots, or small minnows. PM me if you have any other specific questions, I'll be glad to help.
