Hammersmith bridge closure means no river traffic allowed underneath which means the Thames is effectively cut off. If people want to reach the non-tidal Thames they'll have to go via the Regent's Canal (if their boat fits.) The problem is there's no water in the Regent's Canal!

Currently the only possible route is via Limehouse Cut, Lee Navigation, and Hertford Union Canal to the Regent's. But with water supply looking even more precarious (there hasn't been any rain to boost the Regent's water levels) its all touch and go.

The Regent's Canal below Victoria Park's been struggling for days, sometimes boats have been sitting on the bottom & its been closed intermittently to try get levels restored. Today it was shut again (Salmons Lock to Limehouse) in an attempt to get water levels back up.
