39-acre lake in Sudbury District, Ontario. The lake tops out around 90 ft. The depth data here comes from the Ontario MNRF survey of 1981 (a transect sounding survey). Every species below gets its seasonal read from the same numbers driving the chart.
Loon Lake maps at 39 acres behind 1.5 miles of shoreline. With a 1.7 development index there's bank structure worth casting at, in moderation. 40% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Call it 0.4 mi long by 0.3 mi wide at the broadest reach. It sits in Sudbury District. Its nearest charted neighbour, Moon Lake, is 0 mi to the southwest.
Spring brook trout on Loon Lake hold shallow, usually 2 to 15 ft. By summer they slide out to 10 to 30 ft, and by winter most fish are in 3 to 20 ft. The chart's best answer is Main-lake point — point, 11 ft, prime for spring. Prime time lands in early morning and the evening. The summer box starts with a small spoon fished deep or a trolled lake-clear wobbler + worm.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (11 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 | Main-lake point (11 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (2 ft) | Small jigging spoon, Tungsten jig + plastic |
Early season rainbow trout use the shallows, holding in 5 to 20 ft. Expect a summer slide to 8 to 30 ft, then a winter hold in 8 to 40 ft. Put Break off the point first on the milk run — a drop-off near 40 ft that grades prime for winter. In summer the feeding windows fall in early morning and the evening. Tie on a dodger + spoon (deep troll) or a flutter spoon and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 20 ft | dawn & dusk | Main-lake point (11 ft) | Inline spinner (silver), Small spoon |
| Summer | 8 to 30 ft | dawn & dusk | Main-lake point (11 ft) | Dodger + spoon (deep troll), Flutter spoon |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (11 ft) | Casting spoon, Jerkbait over shoals |
| Winter | 8 to 40 ft | dawn | Break off the point (40 ft) | Jigging spoon, Tube jig (white) |
Come spring, look for burbot tight to the bank in 25 to 70 ft. Expect a summer slide to 27 to 90 ft, then a winter hold in 15 to 60 ft. Start at Deep basin. It's a deep basin holding about 85 ft of water and rates prime come summer. Prime time lands in after dark and midday. A heavy jig + cut bait is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (40 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 27 to 90 ft | night & midday | Deep basin (85 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Deep basin (85 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (40 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
