A section of the canal above lock 3 remains in water, although the lock gates have been removed and replaced by weirs. Beyond this section, footpaths follow the course of the canal as far as Hallam wharf. Below lock 3, most of the canal has been filled in as the ironworks have expanded, but a pipe in the bed of the canal still delivers water to the works. The four-storey toll house at the Ladywood Road bridge remained until 1965 when it was demolished by the local council. Mapperley reservoir and Hawley's Pond are still there, but Shipley reservoir has been transformed as its site was occupied by the lake at the centre of The American Adventure Theme Park, until its closure in 2007. Two original bridges connected with the reservoir are located at its southern end. Colliery Road Bridge is a single-arched grade II listed structure built of sandstone and red brick, while Paul's Arm Bridge is of a similar construction but has two arches.
