A disused railway tunnel passes under the Worcester and Birmingham Canal between Gas Street Basin and Salvage Turn. Water has started leaking into the tunnel, presumed to be from the canal, and investigations are required to identify the source of the leak and to fix it.
A pair of temporary dams have been installed with the water pumped out between them.
The first picture, from the footbridge at Worcester Bar shows a workboat moored in the narrows to prevent other boats approaching the dam.
Looking along the canal, from the same footbridge, we can see the blue sheeting for the nearer dam, with the water pumped out from behind.
Alongside the drained section the pump can be seen, running slowly to keep the drained section empty.
The supports for the temporary dam can be seen better from this side.
Viewed from the other end, the drained section is visible between the two temporary dams.
A "fish rescue" has removed all the fish to the main canal and, presumably work will be going on to identifty the leak and to fix it.
