Numbering / naming of the lagoons?

When providing visit reports here and elsewhere, about sightings at Newport Wetlands, it would be useful to identify the lagoons, and maybe other specialist areas, in some way.

I have seen some people on the local GOS site refer to sightings at R1 to R6 but cannot source the reasoning behind this .

Is there any RSPB definitive ID system we could use for the reserve area or if none exists is it possible to instigate one ?

Best regards
Nigel
