How does latitude shift the muskie calendar?
Every phase slides weeks between the range's south and north edges. Tennessee and Kentucky reservoir muskie may spawn in March; southern Wisconsin and Minnesota fish go in late April to mid-May; Ontario shield lakes and Lac Seul country often run into early June — which is exactly why northern seasons open later (Ontario's third Saturday in June, for example). The fall trophy window slides the same way: October in the far north, deep into November on Green Bay or the St. Lawrence. Read every muskie date you see online against the latitude it came from, then correct for yours.
