About this water

It is mainly a spawning stream, which tells you most of what you need to know — the trout are small, averaging half a pound with the odd one to twelve ounces — but they are wild and willing. Heavily overgrown in places, so keep the tackle small and light and your expectations the same. Riparian-owner water; enquire locally.

Hatches & food

An acidic upland granite spate stream and spawning tributary — fly life is sparse and acid-tolerant, dominated by stoneflies and terrestrials with only thin upwings, suiting small wild trout in fast pocket water.
