77-acre lake in Sudbury District, Ontario. The lake tops out around 62 ft. The contours come from a model of the real basin shape and its known max depth. Read them as probabilities, not soundings, and keep them out of navigation decisions. Here's the year, species by species, as the scoring engine sees it.
On the chart, Dorothy Lake draws 76 acres inside 1.7 miles of shoreline. A shoreline index of 1.3 says round and simple: fish relate to depth changes here, not shoreline features. 23% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. End to end it runs roughly 0.6 mi, about 0.3 mi across. You'll find it in Sudbury District. For a second option, Hortense Lake lies 1 mi northeast.
Early season rock bass use the shallows, holding in 2 to 10 ft. Summer is a 5 to 20 ft game here, winter a 12 to 30 ft one. The chart's best answer is Main-lake point — point, 16 ft, prime for summer. Best bite is the evening. Tie on a ned rig (small) or a marabou jig and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (16 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (16 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (28 ft) | Tungsten jig + plastic, Small spoon + spike |
Spring puts burbot in skinny water — 19 to 62 ft is the zone. Summer fish stay in 19 to 62 ft, and winter fish hold in 15 to 60 ft. Deep basin is the standout, a deep basin at roughly 53 ft, rated prime for spring burbot. Plan around after dark and midday in the warm months. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 19 to 62 ft | night & dusk | Deep basin (53 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 19 to 62 ft | night & midday | Deep basin (53 ft) | Heavy jig + cut bait |
| Fall | 19 to 62 ft | night & dusk | Deep basin (53 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Deep basin (53 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
