As I asked the question I should describe my fishery.
A group of lakes with a least one with no carp- so that I could fish light and not get smashed up.
Estate type lakes with depths suitable for float fishing - not too shallow in the margins.
Lily-beds and trees but not too close to swims. Able to park car close and in sight.
Tall fences and locked gates.
Species to include Tench, Crusians, Bream, Roach, Grass carp.
Possibly no King Carp - I can go almost anywhere for those.
Not sure about Rudd as they can be very spraty. Would think carefully about perch - I like big ones but not the tiddlers that swallow your hook.
Perhaps it would be a syndicate so I could avoid irresponsible types who drop litter, cast over muliple swims etc.
It's hard to say what the rules would need to be as until problems arise you dont need to ban things but could be:-
One rod only
No camo
No carpies (sorry but the idea is for a return to proper angling)
No pratice casting
No bait-boats
