31-acre lake in Sudbury District, Ontario. The lake tops out around 140 ft. The depth data here comes from a transect sounding survey by the Ontario MNRF. The rest of this page walks each species through its year, using the map's own scoring.
Whiskeyjack Lake maps at 32 acres behind 1.1 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. Littoral water — the productive band under ~15 ft — makes up 7% of this chart. Tip to tip the water measures near 0.4 mi with a 0.2-mi widest point. It sits in Sudbury District. Partridge Lake sits 1 mi west — the closest neighbouring chart.
Early season lake trout use the shallows, holding in 10 to 40 ft. Expect a summer slide to 50 to 120 ft, then a winter hold in 20 to 80 ft. Put Main-lake point first on the milk run — a point near 38 ft that grades prime for spring. In summer the feeding windows fall in early morning. Tie on a white tube jig (deep) or a magnum spoon on downrigger and you're in the game.
