Last year I contacted John Gallagher (wasn't he a councillor?) about underground rivers, in particular the Warple as he is a bit of an expert on this and he sent me this interesting information:'The river is the Stamford Brook west branch. I have only very sketchy maps with approximate routes in Gwilym Rowland's and the Harper Smith's books. The principal rivers the SB which rises at Gypsey Lane, flows down the west side of Horn Lane, crosses Springfield Gardens, goes round Steyne Road, down Crown Street and along Avenue Road and Warple Way, the Bollo Brooke, which rises in Hanger Hill, flows down to Fordhook Avenue to Acton Town Station and along the lane of the same name and the Bourn, which rises in Friary Park and comes down between Cumberland Park and Goldsmith Avenue and under the Windmill. There is also the east Stamford Brook, which is the boundary between Acton and Hammersmith, rising in the Scrubs and flowing along Old Oak and Askew Roads.'John Gallagher
