About this water

The Scottish Government grades the loch's salmon rivers, the Leven and the Endrick Water, Poor (Grade 3) for 2026, so every salmon must be released all season. Southern basin is broad and shallow, productive for sea trout drifting in summer. Northern part is deep and narrow, home to salmon. Island fishing for sea trout in summer evenings is special. Tributary rivers (Endrick, Fruin) provide wading trout fishing. The loch's scale means boats, strategy, and timing matter; fish concentrate in particular areas depending on season and wind. Powan (freshwater herring) also present. Complex management — check local regulations.
