337-acre lake in Rainy River District, Ontario. The lake tops out around 72 ft. Contours on this water are modeled from its actual shoreline and max depth. Good for finding likely water, never for navigation. The season-by-season read for each species follows, from the map's own numbers.
The drawn water covers 337 acres wrapped in 5 miles of bank, with a single island in the mix. A middling shoreline index (1.9) gives it some bays to work without being a maze. Roughly 61% of the water is 15 ft or less as modeled, the band where the food chain lives. Figure 1.6 mi of water from one end to the other, 0.7 mi at the beam. It sits in Rainy River District. If the bite dies, Whalen Lake is 2 mi to the south.
Spring puts cisco (lake herring) in skinny water — 10 to 40 ft is the zone. As the season builds they drop to 22 to 72 ft, wintering in 20 to 60 ft. Summer cisco (lake herring) concentrate at Deep basin, a prime-rated deep basin around 61 ft. Warm-month bites cluster around early morning. A vertical flutter spoon (small) or a drop-shot micro plastic 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 | 10 to 40 ft | dawn & dusk | Break off the point (32 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 22 to 72 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (61 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 5 to 25 ft | dusk & dawn | open water | Small casting spoon, Inline spinner (silver) |
| Winter | 20 to 60 ft | dawn | Deep basin (61 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Spring northern pike on Day Lake hold shallow, usually 2 to 8 ft. They move out to 8 to 20 ft in summer and finish the year down in 5 to 15 ft. Put Shallow bay flat first on the milk run — a weed flat near 6 ft that grades prime for spring. The feeding windows run early morning and the evening. The summer box starts with a bucktail or a weedless spoon over cabbage.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 8 ft | midday & dawn | Shallow bay flat (6 ft) | #5 inline spinner, Spoon (red/white) |
| Summer | 8 to 20 ft | dawn & dusk | Shallow bay flat (6 ft) | Bucktail, Weedless spoon over cabbage |
| Fall | 6 to 18 ft | midday & dawn | Shallow bay flat (6 ft) | Big rubber (Bull Dawg style), Husky-style jerkbait |
| Winter | 5 to 15 ft | midday | Shallow bay flat (6 ft) | Tip-ups, Large jigging spoon |
Spring puts rock bass in skinny water — 2 to 10 ft is the zone. As the season builds they drop to 5 to 20 ft, wintering in 12 to 30 ft. Summer rock bass concentrate at Main-lake point, a prime-rated point around 18 ft. Warm-month bites cluster around the evening. A ned rig (small) or a marabou jig covers the summer program.
| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 2 to 10 ft | midday & dawn | open water | 1/16 oz jig + grub, Small inline spinner |
| Summer | 5 to 20 ft | dusk | Main-lake point (18 ft) | Ned rig (small), Marabou jig |
| Fall | 8 to 22 ft | midday | Main-lake point (18 ft) | Small tube jig, Inline spinner |
| Winter | 12 to 30 ft | midday | Break off the point (32 ft) | Tungsten jig + plastic, Small spoon + spike |

Anglers target cisco (lake herring), northern pike, rock bass on Day Lake.
Deep basin is the top-rated area: a deep basin in about 61 ft of water that rates prime for cisco (lake herring) in summer. The interactive chart above rates every spot for each species and season.
For cisco (lake herring), the summer bite is best in early morning. Each species page section below lists the seasonal windows, and the map shows a live NOW badge when you're inside one.
