About this water

The Inny is a small Tamar tributary — Cornish in character, rising above Altarnun and running through wooded country to the Tamar near Greystone Bridge. It is principally wild brown trout fishing on Bodmin-fringe water, with sea trout (peal) on the lower beats from mid-June and a small autumn salmon run that follows the lower Tamar. Bealsmill is the only gauge and sits low down, near the Tamar confluence; for the upper river it should be read as a falling-water indicator rather than a real-time level. The Inny has the same kind of intimate pocket-water character as the upper Lynher.
