525-acre lake in Sudbury District, Ontario. The lake tops out around 133 ft. The chart is a model: real shoreline, published maximum depth, interpolated in between. A planning tool, never a navigation product. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Barlow Lake draws 531 acres inside 19.1 miles of shoreline, with 2 islands in the mix. An index of 5.9 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Littoral water — the productive band under ~15 ft — makes up 59% of this chart, as modeled. End to end it runs roughly 4.1 mi, about 1.9 mi across. You'll find it in Sudbury District. For a second option, Nepewassi Lake lies 5 mi northwest.
When the water first warms, lake whitefish slide up into 15 to 45 ft. Summer is a 40 to 90 ft game here, winter a 25 to 70 ft one. Start at Break off the point. It's a drop-off holding about 60 ft of water and rates prime come summer. The feeding windows run early morning. Keep a blade bait vertical or a small jigging spoon rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 15 to 45 ft | midday & dawn | open water | Small jig + waxworm, Blade bait (small) |
| Summer | 40 to 90 ft | dawn | Break off the point (60 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 8 to 30 ft | dusk | Main-lake point (33 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 25 to 70 ft | midday & dawn | Break off the point (60 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Early season walleye use the shallows, holding in 4 to 15 ft. Expect a summer slide to 15 to 35 ft, then a winter hold in 20 to 40 ft. Put Main-lake point first on the milk run — a point near 33 ft that grades prime for fall. In summer the feeding windows fall in the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.

The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
