Farmers can "buy" water for extraction under licence but I believe these licences can be revoked if there is a drought.

It is actually illegal to withdraw water for a watermill and return it to the river except under licence!

In England you also need a rod licence to go fishing. Move to Scotland!

In Orkney nobody owns the lochs under viking law so fishing on the lochs is free.

If you are a landowner with a large run-off should the water board pay you for the water provided by your acrerage?
