I am pleased to say that the water depth indicator is illustrated in the newly published version of TSM Chapter 4, with a note that it needs to be authorised by the relevant national authority.

That’s great news, but a somewhat backward step for a previously prescribed signs to now need site authorisation. Also, it’s a pity that DfT didn’t accede to IHE’s other suggestion for this sign – to replace “M” with “m” as the correct international abbreviation for metres.
