A proper day on the water

River dropping into shape after a lift. Fishing well — get there before it drops out.

The river's easing back into shape after a lift, the water's still cold, around 8°C, and starting to clear.

About this water

The Rangitata is one of the most famous of the Canterbury salmon rivers — a big braided river off the Alps, fished for sea-run chinook through the summer run at its mouth and lower braids, with good brown-trout fishing in the gorge and clearer channels. The salmon fishery is iconic but its stocks are under serious pressure and the rules are restrictive (see regulation note). The braided water demands respect and careful wading.

Under the surface

The Rangitata braids out of the Two Thumb and Arrowsmith ranges across the south Canterbury plains, splitting around long shingle islands below its rugged gorge. A renowned sea-run salmon river, its summer run draws anglers to the mouth and lower braids, while the gorge and clearer channels hold strong brown trout.

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