242-acre lake in Sudbury District, Ontario. The lake tops out around 43 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Mosquito Lake runs 244 acres with 7.8 miles of edge, broken up by an island. An index of 3.5 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. About 73% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 1.9 mi end to end and 1 mi across at its widest. You'll find it in Sudbury District. Closest neighbour on DepthScout: Pistol Lake, 1 mi north of here.
When the water first warms, cisco (lake herring) slide up into 10 to 40 ft. Summer is a 13 to 43 ft game here, winter a 13 to 43 ft one. Start at Deep basin. It's a deep basin holding about 37 ft of water and rates prime come spring. The feeding windows run early morning. Keep a vertical flutter spoon (small) or a drop-shot micro plastic rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Deep basin (37 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 13 to 43 ft | dawn | Deep basin (37 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | Break off the point (19 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 13 to 43 ft | dawn | Deep basin (37 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
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 Break off the point first on the milk run — a drop-off near 19 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.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (11 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 15 to 35 ft | dusk & dawn | Break off the point (19 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 12 to 40 ft | dusk & night | Break off the point (19 ft) | Jigging rap, Jig + big minnow |
| Winter | 20 to 40 ft | dusk & dawn | Deep basin (37 ft) | Jigging spoon + minnow head, Rattle bait |
Spring yellow perch on Mosquito Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 5 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (5 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Break off the point (19 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Deep basin (37 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (37 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Start shallow in spring: burbot sit in 13 to 43 ft that time of year. They don't go far with the seasons — 13 to 43 ft covers summer, 11 to 43 ft covers winter. Top water on the chart: Deep basin, a deep basin in the 37 ft range, prime in spring. Fish it in after dark and midday and you'll meet the bite. Throw a heavy jig + cut bait until the fish tell you otherwise.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 13 to 43 ft | night & dusk | Deep basin (37 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 13 to 43 ft | night & midday | Deep basin (37 ft) | Heavy jig + cut bait |
| Fall | 13 to 43 ft | night & dusk | Deep basin (37 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 11 to 43 ft | night & dusk | Deep basin (37 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
