I have heard of some people catching some fish at Farm Island in years past and also the stilling basin below the dam. I fished the stilling basin years ago and wasn't great, but we did catch a handful of fish. As for Oahe, I believe most decent ice fishing is usually Whitlocks and north. Baits I usually use on the Missouri are a spoon (PK Spoon or Buckshot) tipped with minnow heads, Jigging rap, or a vibratory bait. Good Luck!
