290-acre lake in Sudbury District, Ontario. The lake tops out around 12 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. Species by species, here's what the data says the year looks like.
Traced from the shoreline, Bird Lake runs 294 acres with 5.8 miles of edge. With a shoreline index of 2.4, this water is all arms and coves — edge habitat well beyond its acreage. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. The basin spans about 1.5 mi end to end and 0.7 mi across at its widest. The water lies in Sudbury District. The nearest mapped water is Western Channel (French River), 5 mi to the south.
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Through summer count on 4 to 12 ft; the winter hold is 4 to 12 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.
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 | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 4 to 12 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (10 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 4 to 12 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (10 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 4 to 12 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (10 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: northern pike sit in 2 to 8 ft that time of year. Summer pushes them deeper, 4 to 12 ft, and winter fish settle into 4 to 12 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 | 4 to 12 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (5 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 4 to 12 ft chart-limited; documented 6 to 18 ft | midday & dawn | Break off the point (5 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 4 to 12 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: smallmouth bass sit in 3 to 12 ft that time of year. They don't go far with the seasons — 4 to 12 ft covers summer, 4 to 12 ft covers winter. The spot to know is Main-lake point, a point in about 8 ft of water that rates prime for smallmouth bass in fall. Warm-month bites cluster around early morning and the evening. Throw a drop shot (goby/minnow) or a ned rig until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |
| Summer | 4 to 12 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (5 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 4 to 12 ft chart-limited; documented 8 to 25 ft | midday & dawn | Main-lake point (8 ft) | Jerkbait, Blade bait |
| Winter | 4 to 12 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (5 ft) | Blade bait, Hair jig |
Early season rock bass use the shallows, holding in 2 to 10 ft. Expect a summer slide to 3 to 12 ft, then a winter hold in 4 to 12 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for summer. In summer the feeding windows fall in the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.

| Season | Depth | Best window | Start at | Go-to baits |

| Spring | 2 to 10 ft | midday & dawn | Main-lake point (8 ft) | 1/16 oz jig + grub, Small inline spinner |

| Winter | 4 to 12 ft chart-limited; documented 12 to 30 ft | midday | Deep basin (10 ft) | Tungsten jig + plastic, Small spoon + spike |
Early season pumpkinseed use the shallows, holding in 1 to 8 ft. Expect a summer slide to 2 to 10 ft, then a winter hold in 4 to 12 ft. Put Shallow bay flat first on the milk run — a weed flat near 3 ft that grades prime for spring. In summer the feeding windows fall in the evening and early morning. Tie on a micro tube or a sponge spider (fly) and you're in the game.

Bird Lake is about 12 ft (4 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target yellow perch, northern pike, smallmouth bass, rock bass, pumpkinseed on Bird Lake.
Shallow bay flat is the top-rated area: a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Scroll up to the map for the complete spot list by species and season.
For yellow perch, the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
