intact, although its entrance to the ship canal has been made considerably narrower. It is now accessed through a lock beneath a pedestrian drawbridge, which is used as a buffer to separate the cleaned water of docks 7, 8 and 9 from the relatively untreated water of the ship canal. This is the only route into the redeveloped basins of docks 9 and 7. The lock and drawbridge are mechanised and controlled from the Salford Quays Operations Tower. Dock 7 has been cut off from the ship canal and divided into a series of small basins, linking Piers 6 and 7 by road and pedestrian footbridges. The basins provide a habitat for wildlife and the introduced fish stock. Access is again from Dock 8, at its north eastern end. Dock 6 is retained in largely its original configuration. The smaller basins into which the docks have been divided are all named after North American lakes, reflecting the area's strong trading links the docks had with North America. Upstream of Dock 6 there is a triangular depression in the canal wall on a similar alignment to the other docks: this was originally a second navigable channel under a fixed road bridge. At the end of the 19th century the channel was infilled above the bridge and the remainder retained as a wharf. Later this arm was further truncated into the vestige seen today. While Dock 9 was being built there were plans to construct a further dock (Dock 10) downstream of, and parallel to, Dock 9. Maps from 1921 still show the proposed dock, but it is omitted on later editions. Pomona docks Pomona docks was a set of five docks on the Manchester Ship Canal. Unlike the former docks in what is now Salford Quays, there has been little redevelopment. Dock 5, Ordsall Dock, was a rectangular dock on the opposite bank to the other docks, and was situated directly opposite docks 3-4. Docks 4-2 left the canal at an angle, running east from the canal, each around long, whilst Dock 1 (mostly in the City of Manchester) was somewhat longer at , and ran almost parallel to the canal in a NE direction. Dock 5 was infilled at the end of the 19th century, during the construction of Dock 9. Dock 4 has now been entirely infilled, and almost no trace remains on the ground, although vague outlines of
