The mysterious Doxey Pool can be found on the path that runs across the top of the Roaches, a gritstone escarpment not far from the Staffordshire/Derbyshire border. The pool is relatively small, measuring 49 by 33 feet, but its sinister reputation far exceeds its diminutive size.
Some accounts maintain that this strange body of water is bottomless; others say that it is connected to Blake Mere, another nearby tarn, via a deep subterranean passage. Both pools are reputed to house a malignant mermaid called Jenny Greenteeth, sometimes described as a blue nymph. In 1949, a Miss Florence Pettit claimed to have witnessed a weird creature emerge from the water just before she was about to take a morning swim.
…a great ‘thing’ rose up from the middle of the lake. It rose very quickly until it was 25 to 30 feet tall. Seeming to be part of the slimy weeds and the water, yet it had eyes, and those eyes were extremely malevolent. It pointed its long boney fingers menacingly at me so there was no mistaking its hostility. I stood staring at the undine, water spirit, naiad or whatever it was while my heart raced. Its feet just touched the surface of the water, the weeds and the air. when I dared to look again, the creature was dissolving back into the elements from which it had formed.
Although it's likely that the spirit was a figment of Miss Pettit's imagination, there's still a haunting atmosphere surrounding the mere and it's easy to imagine that otherworldly creatures lie concealed beneath its surface. Whether this atmosphere is due to the pool's isolated location, and grim waters or the presence of an otherworldly nymph is not known. But unfortunately it's definitely not the mermaid.
