Hi Roger
There's a close season at Walthamstow at the moment for Reservoirs 1 and 2/3, but not the High and Low Manards and the other big one I forget the name of. They're across the rod from the office. The hours arent great - its 7 am- 7.30 pm until early May when it goes to 7 - 10 until late July. Thats from the gates opening to closing and theres a bit of a walk to the reservoirs and they'll lock you in if you're in the carp park after closing time. I've sat there a few times with the bobbins going while I'm packing up which can be a bit frustrating, but you can catch in the daytime and evening. Its not cheap either - £15 for the day regardless of the on and off times.
The closed season means that there will be a lot of carpers on the Low Maynard at the moment. Not that its a problem but it does make it busier than after the close season ends at the start of June. Not so bad midweek.
The Low Maynard is the one that features in all the videos and has the reputation now, nobody fishes the 1 which used to be more popular. When I fished it a few years ago there were a lot of fish around 9-11lb, if you got on them you could really fill your boots. They will have grown on and I personally think you're more likely to have a good day on there than the Low Maynard, especially since the best swims will probably be taken on the Low now. But the Low does have bigger fish in it, but fewer, the 2/3 fewer and bigger again.
I would follow the wind, and put plenty of bait in but I've had my best days on there when I haven't filled it in. You might get away with a catapult at 40 yards, you dont have to cast into the middle of the lake on the Low, on the 1 you need to get as near to the island as possible which is a good 80 yard chuck which can make baiting up a bit more difficult. On the Low I'd fish on the Lockwood side, on the 1 on the first swim opposite the island.
They arent fussy - dead reds, red maggots, dendros, pellets and a small popped up boilie will catch if they're in your swim and feeding. Worm kebab seems to be in fashion at the moment.
From what I've seen the sponsored anglers who film videos get to fish nights when nobody else does and their swims are baited up in advance so its not as easy as they can make it look but its a great place for a big bream.
