River Stour and River Stour B?

Astonishingly to me, on August 30th two news items about THE RIVER STOUR appeared at the BBC website, due to the fact that both of them are in the new ENVIRONMENT AGENCY list of the top 10 cleanest rivers in the UK.

What astonishes me is the fact that the two rivers named STOUR (one in Dorset, one in the Black Country) both make the list, as if some kind of disinformation campaign were afoot to confuse the two Rivers of the same name. Why not change one of them, river STEER perhaps? You can be sure that the River Stour I know in B.C has no Salmon jumping in it.

"Others include the River Stour in Worcestershire - previously famed for the rainbow-coloured dyes that flowed into it from carpet manufacturers -"--http://www.bbc.co.uk/news/uk-14710478
