About this water

Upper Ávila-side Tiétar row: a western Gredos granite freestone draining toward the Tagus. This entry should be read as the upper Ávila / Gredos Tiétar, not as the whole cross-border river system. Cold, clear mountain water, pocket water, and pool-and-run structure support wild browns with Iberian genetic importance connected to the wider Gredos conservation story.
