Talk:River Tweed

Length of river
I have provided a reference for the length of the Tweed (156km / 97 miles) whereas no reference had previously been provided. I am concerned however that is possible that the author of the book from which it comes may have taken that figure from Wikipedia in the first instance as it was certainly in the article prior to the publication of the book. I simply don't know. For the record, I have, as with some other watercourses where dubious lengths have been asserted, painstakingly measured its length myself on online 1:25,000 scale OS mapping using a digital tool and determined it at 163.6km / 101.7 miles - I'd be confident of the accuracy of the figure to within about 0.5%. This latter figure is of course original research on my part so cannot be included in the article but it does at least give an idea of what a true figure should look like if and when an editor finds a suitable reference out there! cheers Geopersona (talk) 19:04, 11 August 2022 (UTC)
