81-acre lake in Sudbury District, Ontario. The lake tops out around 89 ft. Bathymetry on this water is estimated from its real outline and maximum depth. Use it to shortlist water, then verify with your electronics — and never navigate by it. Here's the year, species by species, as the scoring engine sees it.
Ross Lake maps at 82 acres behind 2.4 miles of shoreline. With a 1.9 development index there's bank structure worth casting at, in moderation. Littoral water — the productive band under ~15 ft — makes up 43% of this chart, as modeled. End to end it runs roughly 0.7 mi, about 0.4 mi across. It sits in Sudbury District. Its nearest charted neighbour, Cameron Lake, is 2 mi to the southeast.
Early season brook trout use the shallows, holding in 2 to 15 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 3 to 20 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades good for spring. In summer the feeding windows fall in early morning and the evening. Tie on a small spoon fished deep or a trolled lake-clear wobbler + worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | open water | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Start shallow in spring: cisco (lake herring) sit in 10 to 40 ft that time of year. Summer pushes them deeper, 40 to 80 ft, and winter fish settle into 20 to 60 ft. The spot to know is Deep basin, a deep basin in about 76 ft of water that rates prime for cisco (lake herring) in summer. Warm-month bites cluster around early morning. Throw a vertical flutter spoon (small) or a drop-shot micro plastic until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Break off the point (40 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 40 to 80 ft | dawn | Deep basin (76 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Break off the point (40 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
