From the local angling club website: Lymm Dam is a wonderful big water experience set in beautiful surroundings. Depths of the water range from 30ft to 6ft from which, with skill, you will experience superb angling. Species you could catch here are: large Carp, big Pike, Wells Catfish, Eels, good Perch, Roach, Rudd, Chub, big Tench, lots of big Bream to double figures.
SJ6886 : Water Tower An addition rather than a correction. The white building is built in to the old water tower by the chap who did The Diceman tv series. (Can't remember his name) There was a series of programmes following his trials & tribulations during the build.
