Talk:River Tywi

Length of river
It's true that this river is the longest wholly in Wales. . but only if you exclude the marginally longer River Teifi, and the somewhat longer River Usk. The whole issue of Welsh river lengths needs more attention with reliable references yet! Problem is they're hard to come by and OR, no matter how more accurate it may be, doesn't cut it so far as WP is concerned. cheers Geopersona (talk) 09:28, 20 November 2020 (UTC)
