Tanner's Brook

Tanner's Brook is a 7-kilometre (4.3 mi) river that rises in North Baddesley and flows to Southampton Water.

[2] The longest tributary of Tanner's Brook is Hollybrook which joins it in Shirley.

[2] Within Millbrook a small section of the river was culverted during the construction of the Salisbury and Southampton Canal.

[5] This was filled with concrete in 1964 as part of a flood relief project.

[5][6] Originally the river was joined on the mudflats of Southampton Water by Wimpson Stream but with the mudflats being reclaimed by the expanding docks the Wimpson Stream now joins Tanner's Brook before it reaches Southampton Water.
