reservoir / London, ON / FMZ 16Fanshawe 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.

Grind today
Choppy — a 12 km/h average over 5.9 km of fetch keeps you on the north shore with short runs. Gusts spike to 48 km/h at times — check the hourly and time your launch. Good bite potential — the rising barometer leans toward a pickier bite. Fish the north shore where wind stacks bait and keep it tight to cover.

Powerboat
Clear to launch — a 12 km/h S average over 5.9 km of fetch stays well within a powerboat's weight and power; easy to hold position. Gusts spike to 48 km/h at times — time your launch.
Kayak
Clear to launch — a 12 km/h S average over 5.9 km of fetch stays well within a kayak's low, wind-caught profile; easy to hold position. Gusts spike to 48 km/h at times — time your launch.
Canoe
Launchable but exposed — a 22 km/h average gust and 5.9 km of fetch will test an open canoe's shallow draft; put in on the north shore and stay tight to it. Gusts spike to 48 km/h at times — time your launch.
