In deep pools and dark water, silhouette and contrast do the work colour cannot. A fly that reads as black against depth is enough. Fish it broadside, hold the swing, let it hang at the dangle — that is when the best fish take.

How to fish it · for sea trout
When
From dusk into the first half of the night.
Where
Deeper pools and slower glides · hold water and current seams.
Method
Fish dark patterns on a sink-tip or lightly sunk line, especially near structure.
Kit
10 ft #6/7 rod, floating line with a sink-tip option, 8–10 lb fluoro tippet for the swing.
Why this works
Fair — barometric pressure is working for you, but insect activity is the limiting factor today. ⏰ Sea trout become most active after dark, but this stretch closes at 20:45 — before that window fully opens. Fish hard in the last legal hour: overcast skies and warm evenings can bring fish on early even in fading light.

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.
