53-acre lake in Rainy River District, 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. What follows comes from the same scoring engine that paints the spots above.
Drawn out, this is 53 acres of water rimmed by 2.9 miles of bank. That shoreline is heavily fingered (development index 2.8) — bays, points and pockets everywhere, which multiplies the fishable edge. Every acre of it sits shallower than ~15 ft: one big littoral zone, cover and forage throughout. Tip to tip the water measures near 1.1 mi with a 0.4-mi widest point. The water lies in Rainy River District. Closest neighbour on DepthScout: Middle Roland Lake, 1 mi east of here.
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.

In spring, northern pike run shallow here, mostly 2 to 8 ft. Summer pushes them deeper, 3 to 10 ft, and winter fish settle into 3 to 10 ft. Shallow bay flat is the standout, a weed flat at roughly 2 ft, rated prime for spring northern pike. Time it for early morning and the evening. You won't need more than a bucktail or a weedless spoon over cabbage most summer days.
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 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 | Back-bay flat (4 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 3 to 10 ft chart-limited; documented 6 to 18 ft | midday & dawn | Back-bay flat (4 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 3 to 10 ft chart-limited; documented 5 to 15 ft | midday | Back-bay flat (4 ft) | Tip-ups, Large jigging spoon |
In spring, smallmouth bass run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft. Break off the point is the standout, a drop-off at roughly 8 ft, rated prime for winter smallmouth bass. Time it for early morning and the evening. You won't need more than a drop shot (goby/minnow) or a ned rig most summer days.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft chart-limited; documented 3 to 12 ft | dawn & dusk | Main-lake point (2 ft) | Ned rig, Tube jig |
| Summer | 3 to 10 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Drop shot (goby/minnow), Ned rig |
| Fall | 3 to 10 ft chart-limited; documented 8 to 25 ft | midday & dawn | Break off the point (8 ft) | Jerkbait, Blade bait |
| Winter | 3 to 10 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
Come spring, look for rock bass tight to the bank in 2 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. Start at Break off the point. It's a drop-off holding about 8 ft of water and rates prime come fall. Prime time lands in the evening. A ned rig (small) or a marabou jig is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | Main-lake point (2 ft) | 1/16 oz jig + grub, Small inline spinner |
| Summer | 3 to 10 ft chart-limited; documented 5 to 20 ft | dusk | Break off the point (8 ft) | Ned rig (small), Marabou jig |
| Fall | 3 to 10 ft chart-limited; documented 8 to 22 ft | midday | Break off the point (8 ft) | Small tube jig, Inline spinner |
| Winter | 3 to 10 ft chart-limited; documented 12 to 30 ft | midday | Deep basin (9 ft) | Tungsten jig + plastic, Small spoon + spike |
Come spring, look for lake whitefish tight to the bank in 3 to 10 ft. Through summer count on 3 to 10 ft; the winter hold is 3 to 10 ft. Start at Deep basin. It's a deep basin holding about 9 ft of water and rates prime come summer. Prime time lands in early morning. A blade bait vertical or a small jigging spoon is the honest summer answer here.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 10 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (8 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 3 to 10 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (9 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 3 to 10 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (8 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 3 to 10 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (9 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
Structure-wise the chart holds 6 features, led in depth by Deep basin at roughly 9 ft.

Little Roland Lake 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 northern pike, smallmouth bass, rock bass, lake whitefish on Little Roland Lake.
Shallow bay flat is the top-rated area: a weed flat in about 2 ft of water that rates prime for northern pike in spring. Every other rated spot, per species and season, is on the map above.
For northern pike, 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.
