6,341-acre lake in Cochrane District, Ontario. The lake tops out around 16 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. The depth data here comes from the Ontario MNRF survey of 1983 (a transect sounding survey). What follows comes from the same scoring engine that paints the spots above.
Lawagamau Lake maps at 6,369 acres behind 38.7 miles of shoreline — 4 islands included. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Tip to tip the water measures near 10.9 mi with a 2.3-mi widest point. Cochrane District claims this one. If the bite dies, Lake 20J-33 is 5 mi to the north.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

Start shallow in spring: lake whitefish sit in 5 to 16 ft that time of year. They don't go far with the seasons — 5 to 16 ft covers summer, 5 to 16 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 12 ft range, prime in summer. Fish it in early morning and you'll meet the bite. Throw a blade bait vertical or a small jigging spoon until the fish tell you otherwise.
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 | 5 to 16 ft chart-limited; documented 15 to 45 ft | midday & dawn | Sharp break (6 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 16 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (12 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 4 to 16 ft chart-limited; documented 8 to 30 ft | dusk | Gravel shoal (2 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 16 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (12 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
In spring, walleye run shallow here, mostly 4 to 15 ft. Summer pushes them deeper, 5 to 16 ft, and winter fish settle into 5 to 16 ft. Sharp break is the standout, a drop-off at roughly 6 ft, rated prime for fall walleye. Time it for the evening and early morning. You won't need more than a crawler harness on bottom bouncer or a deep crankbait (trolled) most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Gravel shoal (2 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 16 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Sharp break (6 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |

| Winter | 5 to 16 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (12 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: yellow perch in 3 to 12 ft. As the season builds they drop to 5 to 16 ft, wintering in 5 to 16 ft. Top water on the chart: Weed flat, a weed flat in the 3 ft range, prime in spring. Time it for early morning. 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 | 3 to 12 ft | midday & dawn | Weed flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (12 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (12 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (12 ft) | Tungsten jig + spikes, Rattle spoon (small) |
When the water first warms, northern pike slide up into 2 to 8 ft. By summer they slide out to 5 to 16 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 2 ft that scores prime in spring. In summer the feeding windows fall in 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 8 ft | midday & dawn | Shallow bay flat (2 ft) | #5 inline spinner, Spoon (red/white) |

| Winter | 5 to 15 ft | midday | Weed flat (3 ft) | Tip-ups, Large jigging spoon |
When the water first warms, burbot slide up into 5 to 16 ft. There's no big seasonal slide here — summer means 5 to 16 ft, winter 4 to 16 ft. Start at Deep basin. It's a deep basin holding about 12 ft of water and rates prime come spring. The feeding windows run after dark and midday. Keep a heavy jig + cut bait rigged through the warm months.

Start shallow in spring: cisco (lake herring) sit in 4 to 16 ft that time of year. They don't go far with the seasons — 5 to 16 ft covers summer, 5 to 16 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 12 ft range, prime in spring. Fish it in early morning and you'll meet the bite. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
