133-acre lake in Algoma District, Ontario. The lake tops out around 36 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. Every species below gets its seasonal read from the same numbers driving the chart.
Prugh Lake maps at 131 acres behind 3.9 miles of shoreline. With a shoreline index of 2.5, this water is all arms and coves — edge habitat well beyond its acreage. 77% of the surface is littoral (under ~15 ft), per the model — cover, weeds and forage water. Tip to tip the water measures near 1.1 mi with a 0.6-mi widest point. Algoma District claims this one. Its nearest charted neighbour, Hawk Lake, is 2 mi to the west.
Spring brook trout on Prugh Lake hold shallow, usually 2 to 15 ft. They move out to 10 to 30 ft in summer and finish the year down in 3 to 20 ft. Put Break off the point first on the milk run — a drop-off near 16 ft that grades prime for summer. The feeding windows run 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 (9 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (9 ft) | Small spoon (orange), Spinner |
| Winter | 3 to 20 ft | dawn | Break off the point (16 ft) | Small jigging spoon, Tungsten jig + plastic |
Come spring, look for lake trout tight to the bank in 9 to 36 ft. Through summer count on 11 to 36 ft; the winter hold is 9 to 36 ft. If you only fish one area, make it Deep basin: a deep basin around 31 ft that scores prime in summer. Best bite is early morning. A white tube jig (deep) or a magnum spoon on downrigger is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 9 to 36 ft | dawn & dusk | Main-lake point (9 ft) | Casting spoon over shoals, Jerkbait (shallow) |
| Summer | 11 to 36 ft | dawn | Deep basin (31 ft) | White tube jig (deep), Magnum spoon on downrigger |
| Fall | 7 to 36 ft | dusk & dawn | Main-lake point (9 ft) | Heavy casting spoon, Jigging rap over reefs |
| Winter | 9 to 36 ft | dawn | Deep basin (31 ft) | White tube jig, Airplane jig |
Come spring, look for smallmouth bass tight to the bank in 3 to 12 ft. Expect a summer slide to 10 to 30 ft, then a winter hold in 11 to 36 ft. Start at Main-lake point. It's a point holding about 9 ft of water and rates prime come fall. Prime time lands in early morning and the evening. A drop shot (goby/minnow) or a ned rig is the honest summer answer here.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (9 ft) | Ned rig, Tube jig |
| Summer | 10 to 30 ft | dawn & dusk | Break off the point (16 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 8 to 25 ft | midday & dawn | Main-lake point (9 ft) | Jerkbait, Blade bait |
| Winter | 11 to 36 ft | midday | Break off the point (16 ft) | Blade bait, Hair jig |
Come spring, look for burbot tight to the bank in 11 to 36 ft. Through summer count on 11 to 36 ft; the winter hold is 9 to 36 ft. If you only fish one area, make it Deep basin: a deep basin around 31 ft that scores prime in spring. Best bite is 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 | 11 to 36 ft | night & dusk | Deep basin (31 ft) | Glow jigging spoon + cut bait, Rattle bait (dark) |
| Summer | 11 to 36 ft | night & midday | Deep basin (31 ft) | Heavy jig + cut bait |
| Fall | 11 to 36 ft | night & dusk | Deep basin (31 ft) | Glow spoon + minnow head, Blade bait (slow) |
| Winter | 9 to 36 ft | night & dusk | Deep basin (31 ft) | Glow tungsten + cut bait, Rattle spoon + minnow head |
