The Whiteadder Angling Association controls a large tract of Brown Trout fishing from the foot of the Whiteadder Dam in the Lammermuirs to near Chirnside. The River Whiteadder is the furthest downstream tributary of the River Tweed, flowing into the tidal section near Berwick-upon-Tweed. The Brown Trout season runs from 15th March to 6th October. More information on the Whiteadder AA can be found on their website.
