The River Teviot is a declining Atlantic salmon system where declining Atlantic salmon populations are Category 3 under Scottish Government classification; every fish returned matters. Mandatory catch-and-release applies. It rises in the hills above Teviothead, runs north-east through Hawick and Jedburgh, and joins the Tweed at Kelso. Along that course it drains a big agricultural catchment and carries an extraordinary head of wild brown trout along with everything else that runs through the Tweed system: grayling, salmon, sea trout. The trout fishing is the quiet highlight. The fish are big-river fish with big-river expectations, averaging around half a pound on the main river with fish to a pound and a half regularly caught and two-pounders not rare. Hawick Angling Club controls much of the middle river and issues affordable day tickets; the lower beats below Hawick are association and private water; the upper river above Teviothead is intimate burn fishing. Grayling hold through the winter and give the Borders trout fisher something to do between November and March when most Scottish rivers are closed.
