Model this as a River Ewe-Loch Maree system, not just a river. Mandatory catch-and-release applies. Declining Atlantic salmon populations are Category 3 under Scottish Government classification; every fish returned matters. The Ewe runs gin-clear about two miles out of Loch Maree near Poolewe — a four-rod river of four beats and 13 pools, best suited to a double-handed rod and normally fished with a ghillie. Until the 1990s the system was one of Scotland's most famous sea-trout fisheries; the sea-trout stock then collapsed and large sea trout are now scarce. Sell the place honestly — its beauty and its surviving salmon relevance — not false abundance. Sandstone freestone bedrock underlies this river.
