Conestogo Lake
Conestogo Lake is a drowned river valley that forks. Two arms, each about 6 km of flooded Conestogo River channel, meet at the Conestogo Dam — 628 hectares of flood-control reservoir run by the Grand River Conservation Authority.

Cool, with a high of 11° and a low of 1°. Breezy, gusts to 46 km/h. Falling pressure often fires up the bite.

Dry through the launch window
Choppy — a 11 km/h average over 5.7 km of fetch keeps you on the southeast shore with short runs. Gusts spike to 46 km/h at times — check the hourly and time your launch. The bite should be firing — a falling barometer often trips a pre-front feed. Fish the southeast shore where wind stacks bait and keep it tight to cover.
Craft Verdicts
Powerboat
Clear to launch — a 11 km/h NW average over 5.7 km of fetch stays well within a powerboat's weight and power; easy to hold position. Gusts spike to 46 km/h at times — time your launch.
Kayak
Launchable but exposed — a 26 km/h average gust and 5.7 km of fetch will test a kayak's low, wind-caught profile; put in on the southeast shore and stay tight to it. Gusts spike to 46 km/h at times — time your launch.
Canoe
Too rough — a 26 km/h average gust over 5.7 km of fetch overwhelms an open canoe's shallow draft; not a safe launch today. Gusts spike to 46 km/h at times — time your launch.

How it fishes
Y-shaped impoundment with two arms each about 6 km long, 628 ha, formed by the Conestogo Dam (built 1955–1958, first flooded October 1958); the flooding submerged the former village of Hollen.
SourceWalleye, northern pike, and smallmouth bass are the three most-observed and most-caught species across angler-observation platforms.
SourceCold-water release from depth at the dam supports a stocked brown-trout tailwater in the Conestogo River below the dam — a distinct fishery from the lake.
SourceNo recreational stocking record exists for the reservoir in the Fish ON-Line FMZ 16 dataset; its walleye, pike, bass, and crappie appear self-sustaining.
