I’m researching the River Tud – and I’m not getting very far. I know it runs from roughly Dereham to its confluence with the Wensum at Hellesdon Mill. There’s some nice stuff about the old stately home of Costessey Hall being built on its banks – especially as that’s now the site of Costessey Park Golf Club. But where’s the source? Wikipedia says “south of Dereham”. My shiny new OS map of Dereham and Aylsham sort of agrees, with the line of blue running out somewhere closet to Spurn Farm. Meanwhile a book on Shipdham claims that it is the source for the Yare, the Wissey and the Tud, although it gives the vicinity for the Tud rather vaguely as “near Thomas Bullock Primary School”. Away from the source, where can I get a good photo of it, is there any sort of vista at Hockering or North Tuddenham for example? For the moment we’ll have to live with this view in winter sunlight taken between Longwater Lane in Costessey and the golf course. It’s a modest little river but I think it deserves more than the 200-odd words I’ve so far mustered.All info welcome.
