I spoke to the 'right' CRT guy for this stretch this afternoon. The repair at Shardlow is done and they are now waiting for the levels to rise. There have been 8 CRT guys on the stretch today (they do indeed work weekends!) - water being sent down from the sluices at Wychnor, through Stenson and on down. (Boaters have been letting water through intervening locks (which, he says, is only robbing Peter to pay Paul and not helping at all) so they'd be glad if everyone would just wait.)
They're HOPING the level will have risen enough by tomorrow (Sunday) lunchtime but they won't know till nearer the time. As soon as it's safe to do so they'll open the navigation.
The central message from CRT is there is no repair work to be done, it's just a matter of the water level. All being well, things will be moving again tomorrow afternoon.
