Still some good bream in the lake to low doubles, but I'm going back a while. The key is to fish these places rather than ask others. Because if you know its good others do, and it gets fished. Places like Blickling can go under the radar for quite some time, then pop up with a huge Rudd to a pleasure angler. Then its hammered again, try find some places of your own, and keep them to yourself if you can?
I have not fished blickling for a while, the main reason is the car park is no longer free so you have to pay £5 to park your car and £7 for a day ticket. Not worth it in my opinion. The only species worth fishing for were Bream so as there are plenty on the broads I haven't bothered.
