has any one got any advice or tips i would be gratfull

You're not based in Britain then...? Weedy rivers are either a thing of the distant past or a thing of the fast approaching close season, here...

yer i am born and based in cambridgeshire the river is the river lark its in prickwillow not very often fished and the strech i fish is down a long farm road
what i will say though is that a few months ago they did dredge the river just not the part i fish
also they have cut down all of the trees on the parts they dreged i have herd its cause the leaves were falling in the river
thanks

I fished that river back in the early 1970's had some nice roach, perch, etc in it, it was fairly weedy as well.We used to walk along until we found a reasonable swim fish for chub, roach,and the odd bream the weed was cut back regularly then......But it sounds like things have deteriorated,have a word with the tackle shop in Ely or Cambridge. Plus there was a fella in Wicken who sold day tickets for a Cambridge club the Albion I think, who may be able to help?......Where I fished it was fairly shallow and not to wide.
