I've fished the Garrison in the past. I was on there from 98 through to around 2004/05. It's a great little water. Lots of features, pads, weed, gravel patches etc. All very close up stuff and the carp used to be very clued up.
I have some great memories of the place. Ranging from the work parties where we built new paths and swims, through to the beautiful misty summers morning with the haze of the sun coming through the trees onto the water.
Strangely enough my nickname comes from my time on the Garrison. I finally landed the lakes biggest fish after a lot of trying, and I was shaking so much that I couldn't even manage to un-hook her, so i shouted for help. I was still shaking about 4 hours later when a few of the guys came down to see me
