About this water

The Aparima is a fine, less-pressured western Southland brown-trout river — a friendly medium freestone with good gravel runs and glides, clearer and more intimate in its upper reaches, broad and steady lower down. It fishes the full Southland repertoire: the afternoon mayfly rise, sight nymphing through the runs, and summer terrestrials. A good choice to spread pressure off the more famous rivers.

Under the surface

The Aparima runs from the Takitimu mountains down through western Southland farmland to the Jacobs River estuary, a friendly medium freestone of gravel runs and willowed glides. Less storied than its neighbours but a genuinely good brown-trout river, its upper reaches clear and intimate, the lower river broad and steady.

Wading: Slick gravel, didymo, colour after rain — wadeable with care
