Thanks it has taken a long time and for some of the long gone obscure canals a lot of research as well.
It isn't supposed to be a navigation map as I've included disused and long destroyed waterways, and others have the navigation side of things well covered.
You'll find that Ireland is complete for locks, bridges and other features, Brian at https://irishwaterwayshistory.com helped with this and for the UK I've done:
River Thames
Grand Union Canal
Kennet & Avon Canal
Somerset Coal Canal
Wilts & Berks Canal
Thames & Severn Canal
Bridgewater & Taunton Canal
Itchen Navigation
Portsmouth & Arundel Canal
Wey & Arun Canal (This one has even more detail as I'm a trust member)
Baybridge Canal
Sussex Ouse Navigation
River Medway
River Stour (Kent)
River Wey
Basingstoke Canal
Monkland Canal
Currently doing the Oxford canal from Hawksbury junction down.
