392-acre lake in Wellington County, Ontario. The lake tops out around 10 ft. The depth data here comes from the Ontario MNRF survey of 1971, a decades-old survey (a transect sounding survey). What the data behind the map says about each species, season by season:
Puslinch Lake maps at 393 acres behind 4.6 miles of shoreline, broken up by 5 islands. A middling shoreline index (1.7) gives it some bays to work without being a maze. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. End to end it runs roughly 1.1 mi, about 0.9 mi across. Wellington County claims this one. Grand River section sits 8 mi west — the closest neighbouring chart.
The spring pattern is a shallow one: walleye in 3 to 10 ft. The depth story barely changes: 3 to 10 ft through summer, 3 to 10 ft in winter. 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.

|---|---|---|---|---|
| Spring | 3 to 10 ft | dusk & dawn | Main-lake point (3 ft) | 1/8 oz jig + minnow, Hair jig |

In spring, yellow perch run shallow here, mostly 3 to 10 ft. Summer keeps them at 3 to 10 ft, and they winter in 3 to 10 ft.

You won't need more than a drop-shot micro plastics or a small spoon tipped with worm most summer days.
