Land
The River Tweed catchment is surrounded by five (more or less) groups of hills: the Lammermuirs, the Moorfoot Hills, the Tweedsmuir Hills, Keilder HIlls and the Cheviots.
The hills on the southern side terminate in The Cheviot on their eastern end and to the south almost connect with the Pennines, the Carlisle – Hexham gap however, separating them. To the west, the hills around Tweedsmuir separate the river from the catchments of the Annan and the Clyde while to the north, the Moorfoots and Lammermuirs divide it from the catchments of the rivers of the Firth of Forth.
The Tweed Forum have produced the Tweed Catchment Management Plan that identifies issues relating to the use, improvement and protection of the Tweed's water and sets out clear objectives and actions to meet them. The Tweed Catchment Management Plan can be viewed here.
