31-acre lake in Cochrane District, Ontario. The lake tops out around 90 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. Below is the species-by-species picture, pulled from the same data the map uses.
Green Lake maps at 30 acres behind 1.1 miles of shoreline. A middling shoreline index (1.5) gives it some bays to work without being a maze. The shallow band under 15 ft claims about 24% of the surface on the model — that's where the groceries are. Tip to tip the water measures near 0.5 mi. Cochrane District claims this one. Wiskin Lake sits 0 mi west — the closest neighbouring chart.
Come spring, look for brook trout tight to the bank in 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. If you only fish one area, make it Shallow bay flat: a weed flat around 6 ft that scores good in spring. Best bite is early morning and the evening. A small spoon fished deep or a trolled lake-clear wobbler + worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Shallow bay flat (6 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 | open water | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Shallow bay flat (6 ft) | Small jigging spoon, Tungsten jig + plastic |
Spring lake trout on Green Lake hold shallow, usually 10 to 40 ft. They move out to 27 to 90 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 77 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 (23 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 27 to 90 ft | dawn | Deep basin (77 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 10 to 50 ft | dusk & dawn | Main-lake point (23 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 20 to 80 ft | dawn | Deep basin (77 ft) | White tube jig, Airplane jig |
Early season splake use the shallows, holding in 5 to 25 ft. Summer is a 25 to 60 ft game here, winter a 10 to 45 ft one. The chart's best answer is Break off the point — drop-off, 41 ft, prime for summer. Best bite is early morning and the evening. Tie on a trolled spoon at the thermocline or a white tube jig (deep) and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Main-lake point (23 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 25 to 60 ft | dawn & dusk | Break off the point (41 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 10 to 35 ft | dawn & dusk | Main-lake point (23 ft) | Casting spoon, Jerkbait |
| Winter | 10 to 45 ft | dawn | Break off the point (41 ft) | Jigging spoon tipped with minnow head, Small white tube |
