Caddisflies
Gammarids
Eastern Pyrenean river flowing from high mountains toward the Méditerranée through Spain-adjacent terrain. Geology shifts between granite and schist. Wild brown trout water, 1st-category. Short, spate-responsive character. Best from spring through early summer when snowmelt provides good volume. Technical mountain water — small streams upper, better volume lower. Check local regulations.
Hatches & food
In the Pyrenean gaves and headwater torrents, resident brown trout move from early-season olives and March browns into strong spring and early-summer stonefly activity, then a long spell of evening caddis and small buzzers, with terrestrials most relevant on wooded lower gaves and much less important high above the tree line.
