reservoir / FMZ 16Pittock Lake
Pittock Lake is the Thames River backed up behind a flood-control dam on the edge of Woodstock — 10 km of long, narrow, green water run by the Upper Thames River Conservation Authority. It runs shallow and warm, nutrient-rich enough to bloom in a hot summer, and deepens only toward the Pittock Dam at the west end.

Marginal today
Choppy — a 12 km/h average over 6.2 km of fetch keeps you on the northeast shore with short runs. Gusts spike to 54 km/h at times — check the hourly and time your launch. Good bite potential — with bright sun, dawn and dusk are your windows. Fish the northeast shore where wind stacks bait and keep it tight to cover.
Craft Verdicts
Trailer launchCarry-in launch6.2 km max fetchPressure steady (-1.4 hPa/24h)
Powerboat
Clear to launch — a 12 km/h SW average over 6.2 km of fetch stays well within a powerboat's weight and power; easy to hold position. Gusts spike to 54 km/h at times — time your launch.
Kayak
Launchable but exposed — a 23 km/h average gust and 6.2 km of fetch will test a kayak's low, wind-caught profile; put in on the northeast shore and stay tight to it. Gusts spike to 54 km/h at times — time your launch.
Canoe
Too rough — a 23 km/h average gust over 6.2 km of fetch overwhelms an open canoe's shallow draft; not a safe launch today. Gusts spike to 54 km/h at times — time your launch.

How it fishes
In 2016 UTRCA and partners built a purpose-made fish-habitat complex in the reservoir: 300 tonnes of river stone for shoals and gravel spawning beds, 125 metres of wooden cover structures, plus shoreline and aquatic plantings — targeting bass, pike, perch, walleye and pumpkinseed.
SourcePittock Dam was built 1964–1967 (about $6M) for flood control and summer low-flow augmentation of the Thames through Woodstock and downstream to London.
SourceThe reservoir is 10.3 km long with about 452 ha of summer surface area and a 50 ha cattail marsh at its upstream end; it is a designated Important Bird Area (ON027) known for fall waterbird concentrations on the drawdown mudflats.
SourceNo stocking record exists for Gordon Pittock Reservoir in the Ontario Fish ON-Line FMZ 16 dataset; the warm-water fishery is self-sustaining, and the 2016 project added spawning habitat rather than fish.

Access notes
Pittock Conservation Area
1st Launch (north shore, west basin near the Day Use area / Oxford Yacht Club)
Motorized trailer launch; permit and fee required. Motorized launching is north-shore only, dawn to dusk during the May–October operating season; no personal watercraft. A boat pass does not guarantee season-long access — drawdown can close the launch.
Access sourcePittock Conservation Area
2nd Launch (north shore, near the campground, mid-reservoir)
Second motorized launch shown on the CA boating map; north-shore only, same operating rules and drawdown caveat.
Access sourceRoth Park (south shore, City of Woodstock / UTRCA)
Shore fishing and non-motorized / carry-in launch (Woodstock Dragon Boat Club); paved South Shore / Pittock trail network reaches the dam.
