Whitley Pool, Trench Pool, Crab Mill Flash, Plex Flash, Big Moor, Grey Mist Mere, Spring Pool, Birch Grove, The Mangrove, King George V, Smith's, Village Pool, Gorsty Hall, Betley Mere, Leg O'Mutton (st Helens), Leg O'Mutton (Stoke), Brereton Heath, Hawkstone Park (both), Patshull Church, Halsnead Park, Selby Three Lakes, Tunstall Park, Blackroot, Salford Park, Cuttle Mill (both lakes), Packington Somers (two lakes), Paradise Pool, Moston Flash, Pool Hall and probably a dozen more I can't remember.
Any of those grab you?
