The Waimakariri is Canterbury's most accessible salmon river — a big braided glacial river right on Christchurch's doorstep, fished hard for sea-run chinook at the mouth and lower braids through the summer run, with brown trout in the gorge and clearer channels.

About as good as it gets

River dropping into shape after a lift. The kind of afternoon you tell people about later.

The water temperature is around 12°C, about where the trout want it, the river's easing back into shape after a lift, and starting to clear.

About this water

The Waimakariri is Canterbury's most accessible salmon river — a big braided glacial river right on Christchurch's doorstep, fished hard for sea-run chinook at the mouth and lower braids through the summer run, with brown trout in the gorge and clearer channels. Convenient and popular, with all the braided-river hazards and the same restrictive, conservation-first salmon rules (see regulation note).

Under the surface

The Waimakariri — 'cold rushing water' — braids down from the Southern Alps through its great gorge and across the plains to the sea just north of Christchurch, a wide shingle river of grey glacial channels. The most accessible of the Canterbury salmon rivers, its lower braids and mouth fill with anglers for the summer chinook run, while the gorge holds good trout.

Wading: Braided glacial channels, cold pushy water, unstable shingle, salmon mouth crowds — serious care
