Chizzers & TM, I regulary fish the Bollin and if you know where to go there are some cracking wild brownies up to 5lb.
The Birken Fly Fishing Association has the stretch of the Bollin from up stream of Hale golf club down to the bridge by the large roundabout at Altrincham, as well as many miles of the Birken. The Birken produces more fish and larger fish due to the stocking but for me the Bollin is my go to water, its wild, unkempt and I have never seen another angler on the water and its easy to kid yourself its YOUR water
ps there's some nice chub, perch & pike to be had on the fly as well
