Marginal today

Choppy — a 11 km/h average over 2.6 km of fetch keeps you on the north shore with short runs. Gusts spike to 47 km/h at times — check the hourly and time your launch. Good bite potential — with bright sun, dawn and dusk are your windows. Fish the north shore where wind stacks bait and keep it tight to cover.

Trailer launchCarry-in launch2.6 km max fetchPressure steady (-1.2 hPa/24h)

Powerboat

Clear to launch — a 11 km/h S average over 2.6 km of fetch stays well within a powerboat's weight and power; easy to hold position. Gusts spike to 47 km/h at times — time your launch.

Kayak

Marginal

Launchable but exposed — a 24 km/h average gust and 2.6 km of fetch will test a kayak's low, wind-caught profile; put in on the north shore and stay tight to it. Gusts spike to 47 km/h at times — time your launch.

Canoe

No-go

Too rough — a 24 km/h average gust over 2.6 km of fetch overwhelms an open canoe's shallow draft; not a safe launch today. Gusts spike to 47 km/h at times — time your launch.

How it fishes

Largest kettle lake in North America

Source

Hosts one of only a few known banded killifish populations in the entire Grand River basin

Source

54 official stocking events 1946–1990 across six species, including more than 1.36 million walleye fry, fingerlings, and eggs from 1947–1979

Source

The Puslinch Lake Conservation Association (founded 1997) has run a multi-decade restoration: walleye spawning stones placed off Harvey's Island in 1998, and dredging that removed more than 400,000 tons of sediment by 2023

Northern pike were never stocked — they're believed to stem from an inadvertent 1950s introduction, and are now the lake's most-caught species
