reservoir / Flesherton, ON / FMZ 16Lake Eugenia
Lake Eugenia is drowned farmland with a hydro dam bolted on the end. The Beaver River valley above Flesherton was dammed in 1912 and the fields went under soon after — nobody cleared them first, so the whole basin is stubbled with submerged stumps, logs, and standing timber.

Grind today
Choppy — a 17 km/h average over 4.1 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.
Craft Verdicts
Trailer launchCarry-in launch4.1 km max fetchPressure rising (6.8 hPa/24h)
Powerboat
Clear to launch — a 17 km/h S average over 4.1 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
Launchable but exposed — a 30 km/h average gust and 4.1 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 48 km/h at times — time your launch.
Canoe
Too rough — a 30 km/h average gust over 4.1 km of fetch overwhelms an open canoe's shallow draft; not a safe launch today. Gusts spike to 48 km/h at times — time your launch.

How it fishes
One of Ontario's older hydro reservoirs: the dam on the Beaver River was built in 1912, and about 1,900 acres of farmland were bought and flooded after 1913.
SourceExtreme shallow-bowl morphology — roughly 40 ft at its deepest against a mean of about 4.6 ft — over flooded farmland full of stumps and standing timber.

Access notes
Lake Eugenia Public Boat Launch & Beach
Canrobert Street (251 Canrobert St, Eugenia/Flesherton), southwest shore
The only municipal public access; all other shoreline is private. Operated by the Eugenia & District Community Improvement Association under MOU with the Municipality of Grey Highlands; 2026 season opens May 8. Motorboat launch fee (~$17/day incl. parking per association info sheet; rates change yearly); canoes/kayaks launch free. Submerged stumps and timber are a basin-wide navigation hazard, worsened by the OPG reservoir's winter drawdown.
