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.
In Galicia's Atlantic trout rivers, resident browns feed through a spring build-up of olives and other up-wings into a long summer of caddis and small buzzers, with frequent spates and cool water keeping fish active; terrestrials from lush banks and meadows become important once levels settle and the banks green up.
