The Loch Lomond system – including the loch itself, which at twenty one miles long and covering an area of 17,500 acres, is Scotland’s largest loch, the major tributaries Fruin and Endrick, and the River Leven which runs the short distance from Balloch to enter the Firth of Clyde at Dumbarton – can produce up to 1500 salmon and a similar number of sea trout. Most of the fishing on the system is managed by the Loch Lomond Angling Improvement Association, who issue day, week and season permits.
The main tributary, the River Endrick, rises in the Fintry hills to flow for twenty miles westwards via Fintry, Balfron and Killearn and over the “Pots” of Gartness before entering Loch Lomond near Balmaha. At one time one of the premier sea trout fisheries in Scotland, the runs of migratory fish on the Endrick have declined dramatically since the mid eighties. Much of the river can be fished by members of the Loch Lomond Angling Improvement Association, which is open to all (subject to a maximum membership limit) for the price of a yearly subscription. The Association is working hard to reverse the decline in stocks and applications for membership, which includes the fishing on Loch Lomond, the River Leven and the River Fruin, should be directed to tackle shops in the Glasgow area or online via the association website above.
