Stamford Brook was a tributary of the Tideway stretch of the River Thames in west London supplied by three headwaters. Historically used as an irrigation ditch or dyke the network of small watercourses had four lower courses and mouths. History Etymology The name Stamford Brook may be a corruption of "stony ford", for a crossing by King Street. It has given its name to the surrounding area between Hammersmith and Chiswick, and to the local London Underground station, Stamford Brook. The county of London created in 1889 was bounded by the westernmost course of Stamford Brook; it formed the boundary separating London Boroughs of Hammersmith and Acton in the new county from the Chiswick and Brentford Urban Districts in Middlesex. By 1900, all six strands of the brook and drainage dykes had been covered over and formed the most useful depressions available in which to site the neighbourhood's sewers, many diversionary surface water drains had been created closer to the surface to drain the catchment basin. Disambiguation Stamford Brook has no known connection with Stamford Bridge, the site of a bridge which carries the Kings Road over the stream to the east called Counter's Creek which rose to the immediate west of Notting Hill. The West London bridge gives its name to Chelsea Football Club's adjoining ground. Course Headwaters A western headwater, the Bollo Brook or Bollar Brook was the westernmost brook feeding the channels running through Chiswick and Hammersmith. This rose on the site of Ealing Common Underground station, midway between Ealing and Acton and travelled south, then southeast, then divided, part was channelled south to Chiswick House and Chiswick; the remainder was channelled into four mouths described below. The main flow travelled east to the north of King Street, Hammersmith. Surface water and foul water drains beside and under short stretches of Piccadilly and District lines followed by the rear of numbers up to 438 Chiswick High Road, then turn ENE follow the lowest depression of that watercourse, cutting across Chiswick Common, crossing the District Line at Turnham Green tube station to reach the formerly seasonally waterlogged, low-lying area of Stamford Brook Common. Fresh water features such as the fishponds by the London Transport Museum Depot on the current location of Acton Town Underground station have been lost due to use of the depression for separate drainage systems. An eastern headwater rose on Old Oak Common in Acton.
