544-acre lake in Ontario. The lake tops out around 10 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 a transect sounding survey by the Ontario MNRF. Here's the year, species by species, as the scoring engine sees it.
On the chart, Pleasant Bay draws 546 acres inside 7 miles of shoreline, broken up by 3 islands. Index 2.1 on the shoreline: a few honest points and pockets, nothing labyrinthine. There is no deep basin to speak of — the entire surface is under ~15 ft, prime weed water end to end. Tip to tip the water measures near 1.9 mi with a 1-mi widest point. For a second option, North Bay lies 1 mi northwest.
Early season walleye use the shallows, holding in 3 to 10 ft. Even in summer they hold at 3 to 10 ft; winter keeps them in 3 to 10 ft. The chart's best answer is Break off the point — drop-off, 4 ft, prime for fall. Best bite is the evening and early morning. Tie on a crawler harness on bottom bouncer or a deep crankbait (trolled) and you're in the game.
Depth note: when a documented seasonal range extends below this chart, the table shows the deepest mapped working water, not a verified holding depth.

Spring yellow perch on Pleasant Bay hold shallow, usually 3 to 10 ft. Depth-wise the year is flat: 3 to 10 ft in summer, 3 to 10 ft once it turns cold. The chart's best answer is Deep basin — deep basin, 10 ft, prime for fall. Prime time lands in early morning. The summer box starts with a drop-shot micro plastics or a small spoon tipped with worm.

Spring puts northern pike in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 3 to 10 ft, wintering in 3 to 10 ft. Spring northern pike concentrate at Shallow bay flat, a prime-rated weed flat around 2 ft. Warm-month bites cluster around early morning and the evening. 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 (2 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 3 to 10 ft chart-limited; documented 8 to 20 ft | dawn & dusk | Break off the point (4 ft) | Bucktail, Weedless spoon over cabbage |

| Winter | 3 to 10 ft chart-limited; documented 5 to 15 ft | midday | Shallow bay flat (2 ft) | Tip-ups, Large jigging spoon |
Spring puts smallmouth bass in skinny water — 3 to 10 ft is the zone. Summer fish stay in 3 to 10 ft, and winter fish hold in 3 to 10 ft. Winter smallmouth bass concentrate at Break off the point, a prime-rated drop-off around 4 ft. Warm-month bites cluster around early morning and the evening. A drop shot (goby/minnow) or a ned rig covers the summer program.

| Spring | 3 to 10 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |

| Winter | 3 to 10 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (4 ft) | Blade bait, Hair jig |
In spring, largemouth bass run shallow here, mostly 2 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring largemouth bass. Time it for early morning and the evening. You won't need more than a texas-rigged 10" worm or a deep-diving crankbait most summer days.

When the water first warms, rock bass slide up into 2 to 10 ft. There's no big seasonal slide here — summer means 3 to 10 ft, winter 3 to 10 ft. If you only fish one area, make it Break off the point: a drop-off around 4 ft that scores prime in fall. In summer the feeding windows fall in the evening. Keep a ned rig (small) or a marabou jig rigged through the warm months.

Pleasant Bay is about 10 ft (3 m) deep at its deepest point. The depth data here comes from a transect sounding survey by the Ontario MNRF.
Anglers target walleye, yellow perch, northern pike, smallmouth bass, largemouth bass, rock bass, pumpkinseed, brown bullhead, common carp on Pleasant Bay. 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.
Break off the point is the top-rated area: a drop-off in about 4 ft of water that rates prime for walleye in fall. Every other rated spot, per species and season, is on the map above.
For walleye, the summer bite is best in the evening and early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
Fishing on Pleasant Bay 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.
