Try a few colors. Northern lurk around piers in 8-15 ft depths early May, try smaller minnow shaped crank baits with smallest leaders you can find. Northern keeper size is 32 in, bass 14, be sure to get Wisconsin visitor license. We were wondering what to expect. She will only be able to fish from shore, so will have very limited access.
Public piers are few and a bit overfished.
Politics of this situation is for another time. Look for casting range into drop offs, if weedy flats close so much the better. Carolina rigged plastics, esp grubbs and small worms, are great shore baits. This is something boaters can avoid. Try a few colors.
