94-acre lake in Nipissing District, Ontario. The lake tops out around 10 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Sasajewun Lake runs 95 acres with 2.5 miles of edge. The shoreline is moderately structured (index 1.9) — enough points and pockets to pattern. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 0.9 mi with a 0.5-mi widest point. You'll find it in Nipissing District. For a second option, Kathlyn Lake lies 1 mi west.
Spring puts brook trout in skinny water — 1 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 2 to 10 ft. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 9 ft. Warm-month bites cluster around early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.

|---|---|---|---|---|
| Spring | 1 to 10 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |

When the water first warms, yellow perch slide up into 3 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. The feeding windows run early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. The feeding windows run the evening and early morning. The summer box starts with a micro tube or a sponge spider (fly).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (3 ft) | Micro jig under a float, Tiny beetle-spin |

Deep basin is the standout, a deep basin at roughly 9 ft, rated prime for winter brown bullhead. Plan around after dark and the evening in the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | dusk & night | Shallow bay flat (3 ft) | |
| Summer | 3 to 10 ft | night & dusk | Shallow bay flat (3 ft) | |
| Fall | 3 to 10 ft | dusk | Deep basin (9 ft) | |
| Winter | 3 to 10 ft | midday | Deep basin (9 ft) |
