River fishermen know how to ‘read’ a river to find the best places to catch trout, in the seam between turbulent and dead water.

In this audio clip recorded in Kelso by the River Tweed, Ronnie Glass, trout fly fishing champion and chair of Kelso Angling Association, explains why trout love the seam, and why fishermen go out on drizzly days.

Recorded by Jules Horne in April 2013 for Working the Tweed.
