at least you know theyre spawning well, went on a walk with my mother with the dogs down barton lane in the attenborough gravel pits, theres a little cut off with clearwater at about 2ft deep and a bridge running over the top, whilst walking over the bridge i look over and saw about 5 or 6 BIG chub and a few roach swimming round!!, i wish i had my rod with me and they would be mine but the sight was amazing!
