The Duke of Northumberland's River runs parallel to the Longford River for much of its length but then diverts somewhere near Bedfont to feed the ornamental lakes in Syon Park (home to said Duke).
And I think that by an accident of history, having been municipalised by the London County Council and the GLC, the Duke's river is now administered by the National Rivers Authority, whereas as the water supply to part of the royal estate, the Longford River is still run by the Royal Parks Agency.
yeah that's it

). Used to be a shopping trolley dumping ground but has now been cleaned up and has a varied aquatic life.
