From the longer Wikipedia page 
The Wenlock Basin, is a 320 metre long canal basin on the Regent's Canal, in the Hoxton area of the London Borough of Hackney. The City Road Basin lies just to the west of Wharf Road and is in the neighbouring London Borough of Islington.
There are private residential moorings at the North end, with their own entrance gate and entryphone on Wharf Road. The basin itself narrows considerably towards the South - and is not deep enough to be navigable by anything other than canoe.
Unlike the Regent's Canal and City Road Basin, Wenlock Basin is not owned or managed by the Canal & River Trust.
