Ebb Tide Strong Fluvial Flows -- The Port of London Authority advise people-powered vessels, in particular; beginners, novices, younger junior (J15's and younger), or any weaker crews, and those that do not usually navigate on the tidal section of the River Thames not to go afloat on the ebb tide.

Fluvial Flows are average -- All river users to navigate with caution and maintain a proper look out.

How the flag colour is determined
Every day at 6 am and 6 pm the lowest tide reading for the Richmond tide gauge is taken for the preceding 12 hours.
- If the value is 2.6 metres or above then the flag is RED.
- If the value is 1.7 metres or above but less than 2.6 metres then the flag is YELLOW.
- If the value is 0 or above but less than 1.7 metres then the flag is GREEN.
- If the value is less that 0 then the flag is BLACK.
