56-acre lake in Timiskaming District, Ontario. The lake tops out around 26 ft. These contours are modeled — built from the real shoreline and the water's maximum depth — so read them as a guide, never as navigation. Every species below gets its seasonal read from the same numbers driving the chart.
Drawn out, this is 57 acres of water rimmed by 2.2 miles of bank. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. About 85% of the surface sits shallower than 15 ft on the modeled chart — that's the weed-and-bait zone. The basin spans about 0.6 mi end to end and 0.5 mi across at its widest. You'll find it in Timiskaming District. Closest neighbour on DepthScout: Milly L., 1 mi north of here.
Spring walleye on Porphyry Lake hold shallow, usually 4 to 15 ft. By summer they slide out to 8 to 26 ft, and by winter most fish are in 8 to 26 ft. The chart's best answer is Break off the point — drop-off, 12 ft, prime for fall. Prime time lands in the evening and early morning. The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 8 to 26 ft | dusk & dawn | Break off the point (12 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 8 to 26 ft | dusk & night | Break off the point (12 ft) | Jigging rap, Jig + big minnow |
| Winter | 8 to 26 ft | dusk & dawn | Deep basin (22 ft) | Jigging spoon + minnow head, Rattle bait |
Early season yellow perch use the shallows, holding in 3 to 12 ft. Summer is an 8 to 26 ft game here, winter an 8 to 26 ft one. The chart's best answer is Shallow bay flat — weed flat, 3 ft, prime for spring. Best bite is early morning. Tie on a drop-shot micro plastics or a small spoon tipped with worm and you're in the game.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 8 to 26 ft | dawn | Deep basin (22 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 8 to 26 ft | midday | Deep basin (22 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 8 to 26 ft | midday & dawn | Deep basin (22 ft) | Tungsten jig + spikes, Rattle spoon (small) |
In spring, northern pike run shallow here, mostly 2 to 8 ft. Midsummer fish sit out in 8 to 20 ft before dropping to 5 to 15 ft for winter. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 3 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (3 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (12 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (12 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (3 ft) | Tip-ups, Large jigging spoon |
