99-acre lake in Algoma District, Ontario. The lake tops out around 15 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 1976, a decades-old survey (a transect sounding survey). Species by species, here's what the data says the year looks like.
Traced from the shoreline, Baldhead Lake runs 99 acres with 3.7 miles of edge, broken up by 2 islands. An index of 2.7 puts the bank firmly in maze territory: point after pocket after cove, every one a casting target. Tip to tip the water measures near 0.6 mi with a 0.6-mi widest point. The water lies in Algoma District. The nearest mapped water is Mijinemungshing Lake, 2 mi to the southeast.
Spring puts brook trout in skinny water — 2 to 15 ft is the zone. Summer fish stay in 5 to 15 ft, and winter fish hold in 2 to 15 ft. Deep basin is the standout, a deep basin at roughly 15 ft, rated prime for summer brook trout. Plan around early morning and the evening in the warm months. A small spoon fished deep or a trolled lake-clear wobbler + worm covers the summer program.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 15 ft | dawn & dusk | Main-lake point (2 ft) | Small inline spinner (gold), Tiny spoon |
| Summer | 5 to 15 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Deep basin (15 ft) | Small spoon fished deep, Trolled lake-clear wobbler + worm |
| Fall | 2 to 15 ft | midday & dawn | Main-lake point (2 ft) | Small spoon (orange), Spinner |
| Winter | 2 to 15 ft chart-limited; documented 3 to 20 ft | dawn | Deep basin (15 ft) | Small jigging spoon, Tungsten jig + plastic |
In spring, rainbow trout run shallow here, mostly 4 to 15 ft. Summer keeps them at 4 to 15 ft, and they winter in 3 to 15 ft. Winter rainbow trout concentrate at Break off the point, a prime-rated drop-off around 4 ft. Fish it in early morning and the evening and you'll meet the bite. You won't need more than a dodger + spoon (deep troll) or a flutter spoon most summer days.

When the water first warms, brown trout slide up into 2 to 15 ft. There's no big seasonal slide here — summer means 5 to 15 ft, winter 2 to 15 ft. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come summer. The feeding windows run after dark and early morning. Keep a spoon at the thermocline or a deep stickbait (night) rigged through the warm months.

| Spring | 2 to 15 ft chart-limited; documented 3 to 25 ft | dawn & dusk | Main-lake point (2 ft) | Stickbait off planer boards (shallow), Small spoon along mud lines |
| Summer | 5 to 15 ft chart-limited; documented 25 to 60 ft | night & dawn | Deep basin (15 ft) | Spoon at the thermocline, Deep stickbait (night) |

When the water first warms, walleye slide up into 4 to 15 ft. There's no big seasonal slide here — summer means 5 to 15 ft, winter 5 to 15 ft. Start at Deep basin. It's a deep basin holding about 15 ft of water and rates prime come winter. The feeding windows run the evening and early morning. Keep a crawler harness on bottom bouncer or a deep crankbait (trolled) rigged through the warm months.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 15 ft | dusk & dawn | Break off the point (4 ft) | 1/8 oz jig + minnow, Hair jig |

When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 5 to 15 ft, and by winter most fish are in 5 to 15 ft. If you only fish one area, make it Deep basin: a deep basin around 15 ft that scores prime in fall. In summer the feeding windows fall in early morning. Keep a drop-shot micro plastics or a small spoon tipped with worm rigged through the warm months.

The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 5 to 15 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 2 ft range, prime in spring. Time it for early morning and the evening. Summer baits: a bucktail or a weedless spoon over cabbage gets it done.

Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 15 ft.
Season dates, license requirements, and size and bag limits for Ontario waters are set by the Ontario fishing regulations (FMZ summary) — and special regulations can apply to Baldhead Lake specifically, so confirm the current rules before you fish.

Baldhead Lake is about 15 ft (5 m) deep at its deepest point. The depth data here comes from the Ontario MNRF survey of 1976, a decades-old survey (a transect sounding survey).
Anglers target brook trout, rainbow trout, brown trout, walleye, yellow perch, northern pike on Baldhead Lake. This isn't a survey of the lake — none is on record for it — but an informed estimate from the species Ontario's MNRF recorded in the nearest surveyed lakes, filtered to this lake's depth and habitat.
Deep basin is the top-rated area: a deep basin in about 15 ft of water that rates prime for walleye in winter. Every other rated spot, per species and season, is on the map above.
For brook trout, the summer bite is best in early morning and the evening. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Baldhead Lake is regulated by the Ontario fishing regulations (FMZ summary). Check the official Ontario regulations for current license requirements, season dates, and size and bag limits — special regulations can apply to this specific water.
