377-acre lake in Thunder Bay District, Ontario. The lake tops out around 16 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 outline encloses 378 acres, worked by 5.4 miles of shoreline, broken up by an island. With a 2 development index there's bank structure worth casting at, in moderation. The whole water is littoral — nothing here runs deeper than ~15 ft, so it's all weed-and-bait territory. End to end it runs roughly 1.9 mi, about 0.7 mi across. Thunder Bay District claims this one. Mollison Lake sits 2 mi south — the closest neighbouring chart.
The spring pattern is a shallow one: lake whitefish in 5 to 16 ft. The depth story barely changes: 5 to 16 ft through summer, 5 to 16 ft in winter. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates prime for lake whitefish in summer. Plan around early morning in the warm months. Summer baits: a blade bait vertical or a small jigging spoon gets it done.
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 | 5 to 16 ft chart-limited; documented 15 to 45 ft | midday & dawn | Break off the point (7 ft) | Small jig + waxworm, Blade bait (small) |
| Summer | 5 to 16 ft chart-limited; documented 40 to 90 ft | dawn | Deep basin (14 ft) | Blade bait vertical, Small jigging spoon |
| Fall | 4 to 16 ft chart-limited; documented 8 to 30 ft | dusk | Break off the point (7 ft) | Small spoon (gold), Jig + plastic larva |
| Winter | 5 to 16 ft chart-limited; documented 25 to 70 ft | midday & dawn | Deep basin (14 ft) | Jigging spoon + bead chain, Tungsten jig + waxie |
The spring pattern is a shallow one: cisco (lake herring) in 4 to 16 ft. The depth story barely changes: 5 to 16 ft through summer, 5 to 16 ft in winter. The spot to know is Deep basin, a deep basin in about 14 ft of water that rates prime for cisco (lake herring) in spring. Plan around early morning in the warm months. Summer baits: a vertical flutter spoon (small) or a drop-shot micro plastic gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 16 ft chart-limited; documented 10 to 40 ft | dawn & dusk | Deep basin (14 ft) | Small silver spoon, Tiny swim jig (white) |
| Summer | 5 to 16 ft chart-limited; documented 40 to 80 ft | dawn | Deep basin (14 ft) | Vertical flutter spoon (small), Drop-shot micro plastic |
| Fall | 3 to 16 ft chart-limited; documented 5 to 25 ft | dusk & dawn | Break off the point (7 ft) | Small casting spoon, Inline spinner (silver) |
| Winter | 5 to 16 ft chart-limited; documented 20 to 60 ft | dawn | Deep basin (14 ft) | Small jigging spoon (glow/silver), Tungsten jig + minnow head |
Start shallow in spring: yellow perch sit in 3 to 12 ft that time of year. Summer pushes them deeper, 5 to 16 ft, and winter fish settle into 5 to 16 ft. The spot to know is Shallow bay flat, a weed flat in about 3 ft of water that rates prime for yellow perch in spring. Warm-month bites cluster around early morning. Throw a drop-shot micro plastics or a small spoon tipped with worm until the fish tell you otherwise.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 3 to 12 ft | midday & dawn | Shallow bay flat (3 ft) | Small jig + curly tail, Perch-pattern micro crank |
| Summer | 5 to 16 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (14 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 16 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (14 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 16 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (14 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Come spring, look for northern pike tight to the bank in 2 to 8 ft. Expect a summer slide to 5 to 16 ft, then a winter hold in 5 to 15 ft. Start at Shallow bay flat. It's a weed flat holding about 3 ft of water and rates prime come spring. Prime time lands in early morning and the evening. A bucktail or a weedless spoon over cabbage is the honest summer answer here.

Ansig Lake is about 16 ft (5 m) deep at its deepest point. The contours here are modeled from the water's real shape and maximum depth, so treat them as a rough guide.
Anglers target lake whitefish, cisco (lake herring), yellow perch, northern pike on Ansig Lake.
Deep basin is the top-rated area: a deep basin in about 14 ft of water that rates prime for lake whitefish in summer. Scroll up to the map for the complete spot list by species and season.
For lake whitefish, 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.
