Northern Pike fishing at Lake 10N-21
In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 8 to 20 ft, and winter fish settle into 5 to 15 ft. Shallow bay flat is the standout, a weed flat at roughly 4 ft, rated prime for spring northern pike. Plan around early morning and the evening in the warm months.
