A mill is known to have existed at Fulwood in 1641, when Ulysses Fox its builder appeared before the Court of Kings Bench changed with "trespass", as the rights to grind corn were owned by the manor. Despite having to pay £35 8s 9d (£35.43) the mill survived. Later, there were two wheels served by two dams lying between Mill Lane and Mark Lane in Mayfield Valley above Forge Dam. In 1760 the mill was used by Thomas Boulsover for the production of Sheffield-plate buttons. A steam engine was used at the Nether or lower mill from 1847, and both were unused by 1884. The complex was given to Sheffield Corporation in 1937, but most of it has since been demolished. Unlike most installations in Sheffield, the dam impounded the whole of the flow from the Mayfield Brook, with the result that the dam (the normal local term for the lake, rather than the structure that creates the lake) has completely silted up.
