The Bow Back Rivers were dredged a few years ago when they became non tidal, I was not aware that they needed dredging again, certainly not the last few times I have navigated them.
There is only one lock at Bow now, there is hardly the demand for a second one!, Have used it a number of times without seeing it leaking I find it difficult to believe that they leak badly seeing that their are two pairs of gates at the downstram end.
The Bow back rivers are remainder waterways which BW are under no obligation to restore although City Road lock has been restored using others money and now only awiats the installation of gate & paddle gear. Carpenters road lock is being built over by a temporary bridge which will be removed at the end of the games.
The state of these waterways is no worse than when I first boated them 25 years ago and in many respects they arre considerably better. The lagacy from the games will be much improved system in what was a s**t hole of an area.
