50 members for a lake that can cope with no more than 10 anglers is pushing it to say the least.
There is a simple method used by many fisheries and that is to split the 50 members into 2 groups and use a rota system i.e group 1 can fish the lake for the first half of the month and group 2 can fish it for the second half therefor you don't have to wait for more than 2 weeks and you can fish as much as you want during your 2 week period.
There will be people who want to rubbish what I'm saying but this works.
Surely it's better than getting your gear ready then driving to the lake only to find it full, as many of you know the carp in there switch off when there are many lines in the water so a 2 rod limit really should be a must. This coupled with the rota system will improve fishing for everyone.
