958-acre lake in Thunder Bay District, Ontario. The lake tops out around 7 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What follows comes from the same scoring engine that paints the spots above.
Alfred Lake maps at 956 acres behind 14.6 miles of shoreline. A development index of 3.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 5.7 mi long by 0.8 mi wide at the broadest reach. It sits in Thunder Bay District. McQuesten Lake sits 5 mi west — the closest neighbouring chart.
In spring, walleye run shallow here, mostly 2 to 7 ft. Summer keeps them at 2 to 7 ft, and they winter in 2 to 7 ft. Fall walleye concentrate at Break off the point, a prime-rated drop-off around 3 ft. Fish it in the evening and early morning and you'll meet the bite. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) 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 7 ft chart-limited; documented 4 to 15 ft | dusk & dawn | Main-lake point (7 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 2 to 7 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (3 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 2 to 7 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (3 ft) | Jigging rap, Jig + big minnow |
| Winter | 2 to 7 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (6 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 2 to 7 ft. The depth story barely changes: 2 to 7 ft through summer, 2 to 7 ft in winter. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Plan around early morning in the warm months. Summer baits: a drop-shot micro plastics or a small spoon tipped with worm gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| 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 |
| Fall | 2 to 7 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (6 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 2 to 7 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (6 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 7 ft. There's no big seasonal slide here — summer means 2 to 7 ft, winter 2 to 7 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 and the evening. Keep a bucktail or a weedless spoon over cabbage rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 7 ft chart-limited; documented 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 2 to 7 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Shallow bay flat (3 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 2 to 7 ft chart-limited; documented 6 to 18 ft | midday & dawn | Shallow bay flat (3 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 2 to 7 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
Start shallow in spring: lake whitefish sit in 2 to 7 ft that time of year. They don't go far with the seasons — 2 to 7 ft covers summer, 2 to 7 ft covers winter. The spot to know is Deep basin, a deep basin in about 6 ft of water that rates good for lake whitefish in summer. Warm-month bites cluster around early morning. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.

Alfred Lake is about 7 ft (2 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 walleye, yellow perch, northern pike, lake whitefish on Alfred Lake.
Break off the point is the top-rated area: a drop-off in about 3 ft of water that rates prime for walleye in fall. Scroll up to the map for the complete spot list by species and season.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
