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.
| 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 | dusk & dawn | Break off the point (8 ft) | Crawler harness on bottom bouncer, Deep crankbait (trolled) |
| Fall | 5 to 18 ft | dusk & night | Break off the point (8 ft) | Jigging rap, Jig + big minnow |
| Winter | 5 to 18 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.

| Spring | 4 to 18 ft | dawn & dusk | Main-lake point (8 ft) | 3/8 oz jig + ringworm, Hair jig + minnow |

| Winter | 5 to 18 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.

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

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 |
