is this a water tank

Power line here

This trail is barely there, clearly unused for years. Obvious and used trail veers south just north of here, following the branch west to the lake. So from that intersection north is OK, south to here and on south till the end of this segment is dead trail

way/915630121/history has access:foot = yes

Would using foot access tag (see foot=* ) be fitting at least equally well?

Usage statistics are sometimes wrong and should not be blindly followed, but are worth looking at - see http://taghistory.raifer.tech/#***/foot/&***/access%3Afoot/

This is shown as both a cycleway and a driveway, but there's only one road here. What is it really?

This area seems to be slightly offset based off newer imagery

Can't tell if this is a weir here.

shouldn't these Teeboxes be bigger than this? Seems like it should almost just be a node

Worswick Hot Springs is here but missing on the map. Perhaps worth adding it in.
