117-acre lake in Algoma District, Ontario. The lake tops out around 30 ft. The depth chart comes from Ontario Ministry of Natural Resources and Forestry bathymetric survey data, so the contours are survey-derived rather than computer-modeled. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Moon Lake draws 118 acres inside 3 miles of shoreline. The shoreline is moderately structured (index 2) — enough points and pockets to pattern. About 82% of the surface sits shallower than 15 ft — that's the weed-and-bait zone. Figure 0.7 mi of water from one end to the other, 0.7 mi at the beam. The water lies in Algoma District. For a second option, Lower Ritchie Lake lies 1 mi east.
Spring puts lake trout in skinny water — 8 to 30 ft is the zone. Summer fish stay in 9 to 30 ft, and winter fish hold in 8 to 30 ft. Summer lake trout concentrate at Deep basin, a prime-rated deep basin around 30 ft. Warm-month bites cluster around early morning. A white tube jig (deep) or a magnum spoon on downrigger covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 8 to 30 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 9 to 30 ft | dawn | Deep basin (30 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 6 to 30 ft | dusk & dawn | Break off the point (10 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 8 to 30 ft | dawn | Deep basin (30 ft) | White tube jig, Airplane jig |
In spring, splake run shallow here, mostly 5 to 25 ft. Summer pushes them deeper, 9 to 30 ft, and winter fish settle into 7 to 30 ft. Break off the point is the standout, a drop-off at roughly 10 ft, rated prime for summer splake. Time it for early morning and the evening. You won't need more than a trolled spoon at the thermocline or a white tube jig (deep) most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 5 to 25 ft | dawn & dusk | Break off the point (10 ft) | Small casting spoon (gold/orange), Inline spinner |
| Summer | 9 to 30 ft | dawn & dusk | Break off the point (10 ft) | Trolled spoon at the thermocline, White tube jig (deep) |
| Fall | 9 to 30 ft | dawn & dusk | Break off the point (10 ft) | Casting spoon, Jerkbait |
| Winter | 7 to 30 ft | dawn | Break off the point (10 ft) | Jigging spoon tipped with minnow head, Small white tube |
Come spring, look for yellow perch tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 9 to 30 ft. Start at Deep basin. It's a deep basin holding about 30 ft of water and rates prime come fall. Prime time lands in early morning. A drop-shot micro plastics or a small spoon tipped with worm is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 10 to 30 ft | dawn | Deep basin (30 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 9 to 30 ft | midday | Deep basin (30 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 9 to 30 ft | midday & dawn | Deep basin (30 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts burbot in skinny water — 9 to 30 ft is the zone. Summer fish stay in 9 to 30 ft, and winter fish hold in 8 to 30 ft. Spring burbot concentrate at Deep basin, a prime-rated deep basin around 30 ft. Warm-month bites cluster around after dark and midday. A heavy jig + cut bait covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 30 ft | night & dusk | Deep basin (30 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 9 to 30 ft | night & midday | Deep basin (30 ft) | Heavy jig + cut bait |
| Fall | 9 to 30 ft | night & dusk | Deep basin (30 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 8 to 30 ft | night & dusk | Deep basin (30 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
