There is a match at Suffolk Water park I believe. Mostly carp, either on the method or the pole. They will come in on the edge last 2 hours maybe sooner, should be won with 60lb+. Fish 11 to 4 draw 9.45 breckie available, no booking required for breckie. You do need to book for the match but could do that on the morning if nowhere closer turns up. 01473 832327 Post code IP8 4JS. Just west of Ipswich.
How about Lake John, near Waltham Abbey, I think they have opens wednesdays. Loads of skimmers up in the water I believe but have never fished there.
