142-acre lake in Timiskaming District, Ontario. The lake tops out around 67 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. The depth data here comes from the Ontario MNRF survey of 1983 (an MNRF lake survey). Here's the year, species by species, as the scoring engine sees it.
Traced from the shoreline, Peterson Lake runs 144 acres with 4 miles of edge — one island included. That shoreline is heavily fingered (development index 2.4) — bays, points and pockets everywhere, which multiplies the fishable edge. 71% of the surface is littoral (under ~15 ft) — cover, weeds and forage water. Tip to tip the water measures near 0.8 mi with a 0.6-mi widest point. You'll find it in Timiskaming District. Closest neighbour on DepthScout: Crosswise Lake, 1 mi east of here.
Spring yellow perch on Peterson Lake hold shallow, usually 3 to 12 ft. They move out to 10 to 30 ft in summer and finish the year down in 15 to 35 ft. Put Shallow bay flat first on the milk run — a weed flat near 1 ft that grades prime for spring. The feeding windows run early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.
| 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 | Break off the point (7 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 12 to 35 ft | midday | Break off the point (7 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 15 to 35 ft | midday & dawn | Deep basin (59 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Spring puts northern pike in skinny water — 2 to 8 ft is the zone. Warm water sends them out to 8 to 20 ft; cold water stacks them in 5 to 15 ft. Break off the point is the standout, a drop-off at roughly 7 ft, rated prime for fall northern pike. Plan around early morning and the evening in the warm months. A bucktail or a weedless spoon over cabbage covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (1 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Break off the point (7 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Break off the point (7 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Break off the point (7 ft) | Tip-ups, Large jigging spoon |
When the water first warms, pumpkinseed slide up into 1 to 8 ft. Summer is a 2 to 10 ft game here, winter a 6 to 18 ft one. Start at Shallow bay flat. It's a weed flat holding about 1 ft of water and rates prime come spring. The feeding windows run the evening and early morning. Keep a micro tube or a sponge spider (fly) rigged through the warm months.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 1 to 8 ft | midday & dusk | Shallow bay flat (1 ft) | Micro jig under a float, Tiny beetle-spin |
| Summer | 2 to 10 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro tube, Sponge spider (fly) |
| Fall | 4 to 14 ft | dusk & dawn | Shallow bay flat (1 ft) | Micro jig + waxworm, Small spoon tipped |
| Winter | 6 to 18 ft | dawn | Break off the point (7 ft) | Tungsten ice jig + plastic, Tiny spoon |
