Conditions' Indicators (non-tidal):


Caution strong stream
Users of all boats are advised* not to navigate because strong river flows make it both difficult and dangerous. Those in hire boats arriving at a lock where these boards are displayed should stop immediately and contact their hire boat operator to ask for instructions.

arrow_up_fill   Caution stream increasing

Users of all unpowered boats are advised* not to navigate and users of powered boats are advised to find a safe mooring. This is because river flows are likely to strengthen and red boards could be displayed very soon and without warning.


arrow_down_fill   Caution stream decreasing

Users of all unpowered boats are advised* not to navigate and users of powered boats are advised to navigate with caution.

These cautions will be shown as coloured boards on lock gates and overlaid on the interactive map (which will show green when there are no warnings in place)
