The Endrick is the main spawning and holding river of the Loch Lomond system — a small to medium spate stream that drains into the south end of the loch and carries the Lomond salmon and, more famously, the big Lomond sea trout that give this corner of Scotland its reputation. The salmon run is modest but real; the sea trout run is the prize, and in a good year the Endrick fishes as well as anywhere in Scotland for night sea trout through July and into August. Fishing is controlled by Loch Lomond Angling Improvement Association (LLAIA), which also manages Loch Lomond itself — a single permit covers both waters. Day tickets are available via the association and through local outlets around Drymen. Lower reaches are flat and meandering; the middle river above Drymen has better character and faster water.
