269-acre lake in Algoma District, Ontario. The lake tops out around 19 ft. The depth picture is modeled, anchored to the true shoreline and the water's published max depth — a scouting aid, never a chart to run a boat by. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Gull Lake draws 267 acres inside 3.4 miles of shoreline. The shoreline is moderately structured (index 1.5) — enough points and pockets to pattern. The shallow band under 15 ft claims about 89% of the surface on the model — that's where the groceries are. The basin spans about 1.4 mi end to end and 0.5 mi across at its widest. The water lies in Algoma District. For a second option, Pichogen Lake lies 7 mi southeast.
In spring, brook trout run shallow here, mostly 2 to 15 ft. Midsummer fish sit out in 6 to 19 ft before dropping to 3 to 19 ft for winter. Summer brook trout concentrate at Deep basin, a prime-rated deep basin around 16 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a small spoon fished deep or a trolled lake-clear wobbler + worm most summer days.
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 | 2 to 15 ft | dawn & dusk | Main-lake point (8 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 6 to 19 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (8 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 19 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 6 to 19 ft, and winter fish settle into 5 to 15 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for northern pike in spring. Warm-month bites cluster around early morning and the evening. Throw a bucktail or a weedless spoon over cabbage until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 6 to 19 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (9 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (9 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Come spring, look for walleye tight to the bank in 4 to 15 ft. They move out to 6 to 19 ft in summer and finish the year down in 6 to 19 ft. If you only fish one area, make it Break off the point: a drop-off around 9 ft that scores prime in fall. Best bite is the evening and early morning. A crawler harness on bottom bouncer or a deep crankbait (trolled) is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 19 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (9 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 19 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (9 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 19 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (16 ft) | Jigging spoon + minnow head, Rattle bait |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 6 to 19 ft, then a winter hold in 6 to 19 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
