Marginal today
Choppy — a 14 km/h average over 5.7 km of fetch keeps you on the northeast shore with short runs. Good bite potential — steady pressure keeps it predictable. Fish the northeast shore where wind stacks bait and keep it tight to cover.
Craft Verdicts
Trailer launchCarry-in launch5.7 km max fetchPressure steady (0 hPa/24h)
Powerboat
Clear to launch — a 14 km/h SW average over 5.7 km of fetch stays well within a powerboat's weight and power; easy to hold position.
Kayak
Launchable but exposed — a 24 km/h average gust and 5.7 km of fetch will test a kayak's low, wind-caught profile; put in on the northeast shore and stay tight to it.
Canoe
Too rough — a 24 km/h average gust over 5.7 km of fetch overwhelms an open canoe's shallow draft; not a safe launch today.

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.
