Towards the top of the Oldbury Locks there is a branch leading off to the right, which used to led into the Jim Crow Chemical Works.
The phosphorous pollution entering the canal from the chemical works was immense - as can be seen from the first aerial image below.
These days the pollution is gone, but the name lives on as the locks are referred to locally as "The Crow".
