Fanshawe Lake

Fanshawe Lake is the North Thames River backed up behind a flood-control dam on London's northeast edge — 228 hectares of drowned river valley the conservation authority opened in 1953. The water runs brown and nutrient-rich, stained by the river feeding in from the north, and it shallows to a mean near 12 feet before dropping toward 40 down at the Fanshawe Dam.

Marginal today

Choppy — a 12 km/h average over 5.9 km of fetch keeps you on the northeast shore with short runs. Gusts spike to 38 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 northeast shore where wind stacks bait and keep it tight to cover.

Trailer launchCarry-in launch5.9 km max fetchPressure steady (-1.6 hPa/24h)

Powerboat

Clear to launch — a 12 km/h SW average over 5.9 km of fetch stays well within a powerboat's weight and power; easy to hold position. Gusts spike to 38 km/h at times — time your launch.

Kayak

Marginal

Launchable but exposed — a 22 km/h average gust and 5.9 km of fetch will test a kayak's low, wind-caught profile; put in on the northeast shore and stay tight to it. Gusts spike to 38 km/h at times — time your launch.

Canoe

No-go

Too rough — a 22 km/h average gust over 5.9 km of fetch overwhelms an open canoe's shallow draft; not a safe launch today. Gusts spike to 38 km/h at times — time your launch.
