Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Warm water sends them out to 10 to 30 ft; cold water stacks them in 3 to 20 ft. Break off the point is the standout, a drop-off at roughly 27 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
