Thanks pal, Yeah i fished opposite the car park in the corner and fished just off the margin wall and just out in front. I wasnt aware of of the old river bed, i was probably just yards away from it.
I will probably stick to Olivers (as theres a few nice koi in there i wanna get my hands on) and prestons when i get the odd weekdays off so i can grab the swims i want. Thanks for all your help pal.
