Backed by regional invertebrate surveys; no sampling on this exact reach yet.
Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
Spider-heavy and practical. Strong tradition of North Country soft hackles, useful nymphing, and simple dry flies when fish rise properly.
Prysor is a small Snowdonia spate river above Trawsfynydd Lake — narrow water with a good head of wild brown trout to a pound and a half, two short Passport beats, mostly double bank. Properly small fishing on rocks and pockets; six-foot rod, dry-dropper, and a willingness to fish slowly. The kind of river you fish on the way somewhere else and remember after.
