Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

About this water

A Salnés sea-trout river falling from Cuntis through Caldas de Reis to the Ría de Arousa at Cambados. The Umia is a quintessential lower-Galicia reo system — granite freestone water with the spa-spring influence of Caldas de Reis. Wild brown trout in the middle and upper reaches; sea trout running into the lower river from July onwards. Heavily fished by local anglers but reliable through May and June.
