...Just tried to look up the old Waterscape mapping system and it's gone. Shock horror, but I'm not surprised. Typing in the link
https://secure.waterscape.com/map just takes you to the home page. Another money saving cut made in order to line the already heavy pockets in Ivory Towers no doubt. The old maps showed locks, bridges and tunnels etc, in reasonably accurate detail, but now locks, bridges and tunnels are not shown. A load of other less related "stuff" is there now, and accuracy is to the nearest parish. For instance Alvechurch Marina is indicated by a Moorings sign in Droitwich. I don't think I'll bother with it in future.
