157-acre lake in Nipissing District, Ontario. The lake tops out around 20 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. Below is the species-by-species picture, pulled from the same data the map uses.
On the chart, Bear Lake draws 158 acres inside 5.9 miles of shoreline. A development index of 3.4 means a maze of bays and points: far more casting targets than a round bowl of the same size. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Call it 2.4 mi long by 0.4 mi wide at the broadest reach. The water lies in Nipissing District. For a second option, Deer Lake lies 10 mi north.
These fish are listed in an exact-water agency record as forage or ecological context. They are not target-species profiles and do not affect DepthScout's Prime, Good, or Fair spot ratings.

When the water first warms, walleye slide up into 4 to 15 ft. Summer is a 6 to 20 ft game here, winter a 6 to 20 ft one. Start at Deep basin. It's a deep basin holding about 19 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.
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 | 4 to 15 ft | dusk & dawn | Main-lake point (1 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 6 to 20 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Deep basin (19 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 6 to 20 ft chart-limited; documented 12 to 40 ft | dusk & night | Deep basin (19 ft) | Jigging rap, Jig + big minnow |
| Winter | 6 to 20 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (19 ft) | Jigging spoon + minnow head, Rattle bait |
When the water first warms, yellow perch slide up into 3 to 12 ft. By summer they slide out to 6 to 20 ft, and by winter most fish are in 6 to 20 ft. If you only fish one area, make it Deep basin: a deep basin around 19 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.

|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (1 ft) | Small jig + curly tail, Perch-pattern micro crank |

The spring pattern is a shallow one: northern pike in 2 to 8 ft. As the season builds they drop to 8 to 20 ft, wintering in 5 to 15 ft. Top water on the chart: Shallow bay flat, a weed flat in the 1 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.
| 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 | open water | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Deep basin (19 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (1 ft) | Tip-ups, Large jigging spoon |
The spring pattern is a shallow one: smallmouth bass in 3 to 12 ft. As the season builds they drop to 6 to 20 ft, wintering in 6 to 20 ft. Top water on the chart: Main-lake point, a point in the 1 ft range, good in fall. Time it for early morning and the evening. Summer baits: a drop shot (goby/minnow) or a ned rig gets it done.

Spring rock bass on Bear Lake hold shallow, usually 2 to 10 ft. By summer they slide out to 5 to 20 ft, and by winter most fish are in 6 to 20 ft. The chart's best answer is Deep basin — deep basin, 19 ft, prime for winter. Prime time lands in the evening. The summer box starts with a ned rig (small) or a marabou jig.

Spring puts brown bullhead in skinny water — 2 to 8 ft is the zone. As the season builds they drop to 3 to 12 ft, wintering in 6 to 20 ft. Winter brown bullhead concentrate at Deep basin, a prime-rated deep basin around 19 ft. Warm-month bites cluster around after dark and the evening.
