About this water

Canonical Sierra Nevada / Alpujarras headwater row for the Trevélez system. Snow-fed metamorphic geology (schist/phyllite), steep pocket water, and a compressed post-snowmelt season make it fundamentally different from the Cazorla limestone cotos. Use this row as the model for the highest Andalusian trout water rather than treating it with the same longer warm-season logic as the Jaén limestone rivers.
