900-acre lake in Sudbury District, Ontario. The lake tops out around 148 ft. The contours are modeled from the water's real shoreline and maximum depth. Treat them as a rough guide, and never use them for navigation. Species by species, here's what the data says the year looks like.
The drawn water covers 905 acres wrapped in 15.8 miles of bank — 5 islands included. The 3.7 development index tells the story — a convoluted bank whose fishable edge far outruns the acreage. Littoral water — the productive band under ~15 ft — makes up 35% of this chart, as modeled. Figure 3.6 mi of water from one end to the other, 1.6 mi at the beam. Sudbury District claims this one. Its nearest charted neighbour, Linger Lake, is 2 mi to the northeast.
Come spring, look for lake trout tight to the bank in 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. If you only fish one area, make it Deep basin: a deep basin around 126 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (37 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (126 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (37 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (67 ft) | White tube jig, Airplane jig |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 20 to 45 ft. Start at Main-lake point. It's a point holding about 37 ft of water and rates good come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | open water | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Main-lake point (37 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (37 ft) | Jerkbait, Blade bait |
| Winter | 20 to 45 ft | midday | Break off the point (67 ft) | Blade bait, Hair jig |
