At Swansea, the Tennant Canal could be relinked to the Prince of Wales Dock, and hence to the River Tawe, which has become a large marina since the construction of a tidal barrage. This could then provide a link to a restored Swansea Canal. Associated British Ports, who run Swansea Docks, rejected the idea of a canal link in 1997, but since then the Prince of Wales Dock has become the subject of a regeneration scheme, and a route for the canal has been reserved in the planning document. The feasibility of this scheme and a possible route was investigated in a report by the engineers W. S. Atkins published in 2003. A report for Natural Resources Wales by Trilein Ltd. recommended a range of initiatives to better connect the urban areas of the city to the more rural east of the county, including Crymlyn Bog. The reconnection of the Tennant Canal to the Prince of Wales Dock was again outlined in that report.
