82-acre lake in Thunder Bay District, Ontario. The lake tops out around 7 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The rest of this page walks each species through its year, using the map's own scoring.
The drawn water covers 84 acres wrapped in 2.1 miles of bank. A middling shoreline index (1.6) gives it some bays to work without being a maze. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Figure 0.7 mi of water from one end to the other, 0.4 mi at the beam. It sits in Thunder Bay District. If the bite dies, Island Lake is 1 mi to the east.
Spring puts yellow perch in skinny water — 2 to 7 ft is the zone. Summer fish stay in 2 to 7 ft, and winter fish hold in 2 to 7 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Plan around early morning in the warm months. A drop-shot micro plastics or a small spoon tipped with worm 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.

| Spring | 2 to 7 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 2 to 7 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (6 ft) | Drop-shot micro plastics, Small spoon tipped with worm |

Spring northern pike on Wartman Lake hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
