1,694-acre lake in Nipissing District, Ontario. The lake tops out around 18 ft. This chart interpolates between a real shoreline and a known maximum depth. It will point you at likely water, but it is not a navigation product. What the data behind the map says about each species, season by season:
Wasi Lake maps at 1,694 acres behind 12.1 miles of shoreline, with 2 islands in the mix. A middling shoreline index (2.1) gives it some bays to work without being a maze. Littoral water — the productive band under ~15 ft — makes up 86% of this chart, as modeled. Figure 2.5 mi of water from one end to the other, 1.8 mi at the beam. Nipissing District claims this one. Its nearest charted neighbour, Mink Lake, is 3 mi to the north.
The spring pattern is a shallow one: walleye in 4 to 15 ft. As the season builds they drop to 5 to 18 ft, wintering in 5 to 18 ft. Top water on the chart: Break off the point, a drop-off in the 8 ft range, prime in fall. Time it for the evening and early morning. Summer baits: a crawler harness on bottom bouncer or a deep crankbait (trolled) 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 | 4 to 15 ft | dusk & dawn | Main-lake point (8 ft) | 1/8 oz jig + minnow, Hair jig |
| Summer | 5 to 18 ft chart-limited; documented 15 to 35 ft | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 18 ft chart-limited; documented 12 to 40 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 18 ft chart-limited; documented 20 to 40 ft | dusk & dawn | Deep basin (15 ft) | Jigging spoon + minnow head, Rattle bait |
The spring pattern is a shallow one: sauger in 4 to 18 ft. The depth story barely changes: 5 to 18 ft through summer, 5 to 18 ft in winter. The spot to know is Deep basin, a deep basin in about 15 ft of water that rates prime for sauger in winter. Plan around early morning and the evening in the warm months. Summer baits: a bottom bouncer + crawler or a 3-way rig with stickbait gets it done.

| Season | Depth | Best window | Start at | Go-to baits |
|---|---|---|---|---|
| Spring | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |
| Summer | 5 to 18 ft chart-limited; documented 10 to 30 ft | dawn & dusk | Break off the point (8 ft) | Bottom bouncer + crawler, 3-way rig with stickbait |
| Fall | 5 to 18 ft chart-limited; documented 12 to 35 ft | dusk & dawn | Break off the point (8 ft) | Jig + big minnow, Blade bait |
| Winter | 5 to 18 ft chart-limited; documented 15 to 45 ft | dusk | Deep basin (15 ft) | Heavy jigging spoon, Jig + minnow (vertical) |
In spring, yellow perch run shallow here, mostly 3 to 12 ft. Summer pushes them deeper, 5 to 18 ft, and winter fish settle into 5 to 18 ft. Shallow bay flat is the standout, a weed flat at roughly 3 ft, rated prime for spring yellow perch. Time it for early morning. You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.

| 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 18 ft chart-limited; documented 10 to 30 ft | dawn | Deep basin (15 ft) | Drop-shot micro plastics, Small spoon tipped with worm |
| Fall | 5 to 18 ft chart-limited; documented 12 to 35 ft | midday | Deep basin (15 ft) | Jigging spoon (small), Perch rig / spreader |
| Winter | 5 to 18 ft chart-limited; documented 15 to 35 ft | midday & dawn | Deep basin (15 ft) | Tungsten jig + spikes, Rattle spoon (small) |
Early season smallmouth bass use the shallows, holding in 3 to 12 ft. Expect a summer slide to 5 to 18 ft, then a winter hold in 5 to 18 ft. Put Main-lake point first on the milk run — a point near 8 ft that grades prime for fall. In summer the feeding windows fall in early morning and the evening. Tie on a drop shot (goby/minnow) or a ned rig and you're in the game.

| Spring | 3 to 12 ft | dawn & dusk | Main-lake point (8 ft) | Ned rig, Tube jig |

| Winter | 5 to 18 ft chart-limited; documented 20 to 45 ft | midday | Break off the point (8 ft) | Blade bait, Hair jig |
In spring, rock bass run shallow here, mostly 2 to 10 ft. Midsummer fish sit out in 5 to 18 ft before dropping to 5 to 18 ft for winter. Summer rock bass concentrate at Main-lake point, a prime-rated point around 8 ft. Fish it in the evening and you'll meet the bite. You won't need more than a ned rig (small) or a marabou jig most summer days.

Early season brown bullhead use the shallows, holding in 2 to 8 ft. Summer is a 3 to 12 ft game here, winter a 5 to 18 ft one. The chart's best answer is Deep basin — deep basin, 15 ft, prime for winter. Best bite is after dark and the evening.

Wasi Lake is about 18 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 walleye, sauger, yellow perch, smallmouth bass, rock bass, brown bullhead, cisco (lake herring) on Wasi Lake.
Break off the point is the top-rated area: a drop-off in about 8 ft of water that rates prime for walleye in fall. Scroll up to the map for the complete spot list by species and season.
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.
