The lake doesn't stop being worth seeing just because the snow shows up.

Wānaka in winter means one thing to most visitors: Cardrona, Treble Cone, and the drive between them. Fair enough — the season runs from June to mid-October, and the two fields between them cover well over 1,000 hectares of terrain. But the lake doesn't close for the season, and on the right morning, it's arguably better than anything happening on the slopes.
Glassy water, snow-capped mountains, doubled by the reflection.
Less wind, less boat traffic, fewer people out at all. Town temperatures in winter generally sit between 2°C and 10°C — cold, but nowhere near freezing — and on the still mornings that follow a clear night, Lake Wānaka goes genuinely glassy in a way it rarely does once summer's afternoon winds pick up.
Still water means a mirror. On a clear winter morning, the Southern Alps show up on the lake's surface as clearly as they do in the sky — a view you simply don't get once the wind's up.
Winter thins out the crowds without thinning out the scenery. You get more of the lake to yourself at exactly the time of year it looks its best.
If skiing's the reason you're here, the lake is the reason to stay an extra half day. It's a different side of Wānaka most winter visitors never see — and with the ski season running into mid-October, there's a longer window for it than people expect.
It's deep enough — more than 300 metres at its deepest point — that Lake Wanaka never ices over, even through the coldest stretches of July and August. The mountains around it do their full winter transformation; the lake itself just keeps running, open the whole way through.

The mountains aren't going anywhere — see them from the water too, on a lake tour.
