The River Slea is a 36.4-kilometre-long (22.6 mi) tributary of the River Witham, in Lincolnshire, England. In 1872 the river was described as "a never-ending source of pure water", and was a trout river renowned throughout the East coast of England. But in the late 1960s, the Anglian Water Authority took control of the river, and thereafter it became rapidly degraded, due mostly to over-abstraction of water for use in farming.^[2]
