About this water

An intimate limestone stream near Seefeld in the Tyrolean Alps, exceptional clarity and crystal-like purity. Wild brown trout requiring precise dry fly and nymphing. High-altitude headwaters feed flows so clear you feel exposed presenting your fly. Very responsive to rain, very scenic, very rewarding.
