145-acre lake in Sudbury District, Ontario. The lake tops out around 125 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Here is how the season plays out for each species, straight from the data behind the map.
The outline encloses 145 acres, worked by 2.6 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. About 22% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. Figure 1 mi of water from one end to the other, 0.5 mi at the beam. Sudbury District claims this one. If the bite dies, Kerr Lake is 1 mi to the southwest.
Spring lake trout on McGuey Lake hold shallow, usually 10 to 40 ft. They move out to 50 to 120 ft in summer and finish the year down in 20 to 80 ft. Put Deep basin first on the milk run — a deep basin near 106 ft that grades prime for summer. The feeding windows run early morning. The summer box starts with a white tube jig (deep) or a magnum spoon on downrigger.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 10 to 40 ft | dawn & dusk | Main-lake point (31 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 50 to 120 ft | dawn | Deep basin (106 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (31 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Break off the point (56 ft) | White tube jig, Airplane jig |
Spring burbot on McGuey Lake hold shallow, usually 25 to 70 ft. They move out to 50 to 120 ft in summer and finish the year down in 15 to 60 ft. Put Deep basin first on the milk run — a deep basin near 106 ft that grades prime for summer. The feeding windows run after dark and midday. The summer box starts with a heavy jig + cut bait.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 25 to 70 ft | night & dusk | Break off the point (56 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 50 to 120 ft | night & midday | Deep basin (106 ft) | Heavy jig + cut bait |
| Fall | 30 to 80 ft | night & dusk | Break off the point (56 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 15 to 60 ft | night & dusk | Break off the point (56 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
