I sailed down at the river today and noticed an excavator at work at the notch, I tried to go and have a look but got hunted by council staff. A quick google and it reveals that they do intend to breach the sandbar today in preparation for a 3m floodwater rise in the river today. Will it return the heads to the glory days of old, who knows but I hope so....it's a long wait till summer.

Here's a look back in the day...
