321-acre lake in Thunder Bay District, Ontario. The lake tops out around 4 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The season-by-season read for each species follows, from the map's own numbers.
Traced from the shoreline, Blossom Lake runs 321 acres with 3.6 miles of edge. The basin is a simple one (shoreline index 1.4) — close to a bowl, so the structure on the chart matters more than the bank. All of it is shallow-zone water — under ~15 ft across the entire basin, so the food chain has the run of the place. The basin spans about 1 mi end to end and 0.8 mi across at its widest. The water lies in Thunder Bay District. The nearest mapped water is Kekekuab Lake, 5 mi to the west.
Spring yellow perch on Blossom Lake hold shallow, usually 1 to 4 ft. Depth-wise the year is flat: 1 to 4 ft in summer, 1 to 4 ft once it turns cold. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft chart-limited; documented 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 1 to 4 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (3 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 1 to 4 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (3 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 1 to 4 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (3 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 1 to 4 ft is the zone. Summer fish stay in 1 to 4 ft, and winter fish hold in 1 to 4 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Warm-month bites cluster around early morning and the evening. A bucktail or a weedless spoon over cabbage covers the summer program.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 4 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 1 to 4 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 1 to 4 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 1 to 4 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
When the water first warms, lake whitefish slide up into 1 to 4 ft. There's no big seasonal slide here — summer means 1 to 4 ft, winter 1 to 4 ft. If you only fish one area, make it Deep basin: a deep basin around 3 ft that scores good in summer. In summer the feeding windows fall in early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
