Solid today
Choppy — a 12 km/h average over 1.4 km of fetch keeps you on the southeast shore with short runs. Gusts spike to 41 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
Trailer launchCarry-in launch1.4 km max fetchPressure falling (-6 hPa/24h)
Powerboat
Clear to launch — a 12 km/h NW average over 1.4 km of fetch stays well within a powerboat's weight and power; easy to hold position. Gusts spike to 41 km/h at times — time your launch.
Kayak
Clear to launch — a 12 km/h NW average over 1.4 km of fetch stays well within a kayak's low, wind-caught profile; easy to hold position. Gusts spike to 41 km/h at times — time your launch.
Canoe
Launchable but exposed — a 22 km/h average gust and 1.4 km of fetch will test an open canoe's shallow draft; put in on the southeast shore and stay tight to it. Gusts spike to 41 km/h at times — time your launch.

How it fishes
GRCA states northern pike, largemouth bass, smallmouth bass, yellow perch and black crappie "are plentiful in the reservoir"
SourceOne of only four GRCA conservation areas with a supervised ice-fishing program (alongside Guelph Lake, Pinehurst Lake and Belwood Lake)
SourceShade's Mills Dam was built in 1973 as a flood-control dam on Mill Creek: 9.8 m high with 3.2 million m³ of storage — one of the GRCA's seven multi-purpose dams
SourceThe reservoir sits on Mill Creek, a groundwater-fed coldwater stream whose upstream reaches hold brook trout and provincially stocked brown trout (104 km² subwatershed)
Source32-hectare (80-acre) urban reservoir open all year for day use, with an electric-only launch and on-site paddle-craft rentals
