Lancashire 'Nessie'

An angler who has fished this unidentified lake south of Preston, Lancashire, for decades had never seen anything like this before, so videoed it for posterity. He said: "The old jetty behind the unidentified object is about 10 - 12 feet in length so that may present us with some comparative scale.” The YouTuber who confidently states that 'it's a snake' (meaning a grass snake, which do swim well), may have the answer, though.
