Bob….you may find crappies on the upstream side of Trailer Point by drilling holes straight out from shore starting about twenty yards from the sand. The bottom there has a “stair-step” configuration that drops in two to 4 foot drops every four to five feet. Winter crappies will relate to this structure to some degree but they can be hit or miss as they like to travel the whole length of that particular shore and finding/staying with them can be a real pile of work. There’s always an outside chance you’ll snare a walleye or sauger there too but I haven’t seen one over 6 inches from a hole in the ice in years.
Red Wing’s Bayport Marina has quite a bit of fishing opportunity with simple access and depending on where in there you drop a line you can catch sunfish, perch, crappies, northern, walleye/sauger. At the foot end of Pepin in Wabasha you can wet a line in the marina right in town too with great access. I’d opt to fish near the dock closest to the opening to the river in the wide area created there. Typically its and early or late bite. Right across the river on the highway between Wabasha and Nelson Wisconsin you’ll find the back waters are froze up pretty good if you stay where there are tracks in the snow or find where others are fishing. Like anywhere though it can be great or a good reason to go have a beer. Your Minnesota license is good to the railroad tracks on the S’connie side so there’s lots of backwater areas to snoop in.
But if you’re dead set on waldo or his compadre Mr. Saug, you’ll likely do best by staying well north of the Frontenac area but the beach there could be checked to see if you can get bit, stranger things have happened should you catch one. You could take a long rod along too and fish the levee wall in front of the train station in Red Wing paying particular attention to the little pocket created behind the mooring poles. Lots of snags but lots of walleyes and sauger lay in there due to lack of current. Jigs/minnows or bucktails are common baits. Think chartreuse.
Its not that there aren’t walleyes and sauger to be caught….they just aren’t in the old historic locations during the winter anymore.
