Sept 1 though Oct 15 is the St Croix season.
Mike, they bite all year long with spring and fall being the peak.
LOTW’s and The Rainy have a longer season…I THINK it opens back up in July(?). Tom at Wigwam Resort actually guides for them in the summer. Generally Wigwam has some pretty good lodging deals for the week day vacationer, no matter what fish is targeted.
