232-acre lake in Thunder Bay District, Ontario. The lake tops out around 72 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1982 (a transect sounding survey). The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Walotka Lake runs 233 acres with 2.9 miles of edge. Nearly circular (index 1.4), so the story is the bottom, not the bank. Littoral water — the productive band under ~15 ft — makes up 23% of this chart. Figure 1 mi of water from one end to the other, 0.5 mi at the beam. You'll find it in Thunder Bay District. The nearest mapped water is Tease Lake, 4 mi to the south.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Spring puts lake trout in skinny water — 10 to 40 ft is the zone. Warm water sends them out to 22 to 72 ft; cold water stacks them in 18 to 72 ft. Deep basin is the standout, a deep basin at roughly 72 ft, rated prime for summer lake trout. Plan around early morning in the warm months. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

| Summer | 22 to 72 ft chart-limited; documented 50 to 120 ft | dawn | Deep basin (72 ft) | White tube jig (deep), Magnum spoon on downrigger |
