Thought I would expand on the sticker I posted.
The United Kingdom (UK), mainland, is split into three countries England, Scotland and Wales.
Scotland enjoys a different law and legal system from England and Wales. Don’t ask why.
In Scotland you can paddle any waterway, river, burn, creek, loch, lake at any time whatever the day. Not so in England and Wales. Why? In Scotland we enjoy a recent piece of legislation called the Land Reform (Scotland) Act 2003. It allows a statutory right of responsible access to land and inland waters for outdoor recreation, crossing land and some educational and commercial purposes.
England and Wales are trying to establish something similar.
So, here in Scotland everything is all-cool. We go boating on any rivers as and when. Mind you if there is no rain it is difficult.
Hoped this has explained it a wee bitty.
