'20-foot tidal bore. River Nith at Glencaple, 1958
At Glencaple, close to the mouth of the River Nith, on the north shore of the Solway, where the tidal range is considerable and the tidal current strong, the flood tide (from 16 feet upwards) under certain conditions comes in as a bore which may move at a rate of five knots or even more.'
