Traced from the shoreline, Chimney Lake runs 37 acres with 1.9 miles of edge. The 2.2 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 39% of this chart. Figure 0.7 mi of water from one end to the other, 0.2 mi at the beam. You'll find it in Thunder Bay District.

Spring puts splake in skinny water — 5 to 25 ft is the zone. Warm water sends them out to 25 to 60 ft; cold water stacks them in 10 to 45 ft. Break off the point is the standout, a drop-off at roughly 40 ft, rated prime for summer splake. Plan around early morning and the evening in the warm months. A trolled spoon at the thermocline or a white tube jig (deep) covers the summer program.
