You can catch on any bait, boilies seem to be THE bait though..avoid maggots unless you want to get plagued by bream.
John (the owner) netted the lake last December to move some of the biggest ones to his new specimen lake.
There are a few 20+ in there, population I'm not sure but a good amount of carp,(I never blanked there yet).
Good lake for any type of fishing, pole, float, ledger.
I'll keep you updated how we get on tomorrow.
I'd send you the link to their website but it seems the site is not working at the moment. They try to update it daily.
