The feeder burns of the Leader Water are the Headshaw Burn, the Hillhouse Burn and the Kelphope Burn. They combine at the Carfrae mill hotel and the village of Oxton. The river is now sandwiched between the A68 and the A697, and it has absorbed the Cleekhimin Burn, Harry Burn, Washing Burn and Earnscleugh Burn. The Leader Water now passes to the east of the town of Lauder, by Thirlestane Castle. The A679 bridges the river which continues past Lauder Barns, West Mains and St. Leonards where the Leader receives his final feeder burn, the Boondreigh Burn. It now sticks closely by the A68, near the Whitslaid Tower, the Blainslies, Galadean, Birkhill, Chapel-on-Leader and Leadervale. After passing through the outskirts of Earlston, the course of the river is almost done, as it skirts some woodland, and after passing Drygrange, it joins the Tweed at Leaderfoot Viaduct.
