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 Costa da Morte river falling from the Soneira country through Vimianzo to the Ría de Camariñas. The Grande is granite spate water with mixed lowland and broken middle reaches, partial canopy and exposed estuarine sections. Wild brown trout throughout; small reo (sea-trout) population running into the lower river around Camariñas from July onwards. One of the quieter Costa da Morte reo prospects.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
A drop and clear would lift the flow and clarity scores.
The dawn and dusk windows score higher than the midday lull.
