About this water

Classic Black Forest stream with pocket water and broken currents, wild brown trout in intimate terrain. Quick to respond to rain, creating short windows for dry fly during hatches. The river's spate character means timing matters as much as technique.

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