If you want to stay in Iowa, Turtle Creek in St. Ansgar has a ton of stocked trout in it. It can experience summer kill, but the trout generally make it from year to year. It should only be an hour east of you.
As for winter fishing, my two goto flies are the size 6 olive wooly bugger and a size 22 black midge emerger.
