From the Wikipedia page [1] Hammersmith Creek was an outflow river of the Stamford Brook, and used to run through what is now King Street, into the Thames at the present-day site of Furnivall Gardens in Hammersmith. Until the early 19th century the creek was navigable over this distance, and was the scene of much industry with malt houses and boatbuilders along the banks, as well as being a route for cargo transportation.
