I used to fish the River Anker in and around Atherstone back in 93/94. It's a lovely little river with a good little weirpool at Polesworth. I wouldn't put too much hope out for Barbel, I never caught or heard of anyone catching a Barbel from there, not even a fishermans tale, don't take it as gospel though. There are however some nice Chub and Dace, my best being about 3lb and upto about 6-8oz respectively, lovely to catch on a light stick, pound for pound Dace pull a bit. I've witnessed but never caught large Perch, certainly over 2lb, from the weirpool. There used to be a tackle shop adjacent to the pool in Polesworth. For the Barbel, go to the Severn which isn't too far but fish the Anker for some lovely silver bars.
