About this water

The Besaya joins the Saja to form a combined estuary. Official notices reference the Besaya cotos of Somahoz and Iguña. Mixed geology with some urban influence in the lower reaches, but upper sections have genuine wild brown trout character in bouldery runs. Less glamorous than the Saja but relevant for structured trout fishing in managed cotos. SAIH gauge coverage available.
