Caddisflies
Compact Basque spate river flowing into the Bay of Biscay at Ondarroa. Carries Atlantic salmon and sea trout runs typical of the smaller Cantabrian rivers — short, sharp responses to rain, with fish running quickly from estuary to upper beats. Part of the same Basque coastal river family as the Lea and Oka. Atlantic salmon are under serious conservation pressure and managed by cupo (quota), with catch-and-release widely applied; check the current rules before fishing.
The Artibai is a short Basque coastal river, around twenty kilometres from its gathering on the northern slope of Mount Oiz to the Cantabrian Sea at the fishing port of Ondarroa. It rises where mountain streams unite near Iruzubieta and Markina-Jemein and runs down a steep-sided green Bizkaian valley before the tide reaches up from Berriatua to meet it. This is a small, lively river of clear, cool water off the limestone-and-sandstone hills of the Basque country, draining a modest catchment of a hundred and seventy square kilometres through wooded slope and farmland. Like the small rivers of the Cantabrian coast it takes a run of sea trout and salmon up off the sea, the fish dependent on the rain to lift the water. The character is intimate, quick, steep-valley freestone with short pools and runs. Wading is steady on firm rock and gravel, the small clear water rewarding a quiet approach.
Wading: Quiet approach on small clear water
In the steep, often pressured Atlantic rivers of the Basque Country, trout opportunities centre on spring olives and other up-wings when flows and colour briefly line up, with caddis and buzzers helping to sustain sport into early and mid-summer, and terrestrials from grassy, wooded margins adding surface food in quieter, recovering reaches.
