The sawmill fell into disuse before 1806, but by 1817 a lead mill was built on the island, called The Island Lead Mills.
 It continued a thriving business into the twentieth century—it had one of the first telephones in the East End of London—and its barges used the Cut; the company ceased to exist only in 1982.

By about 1868, however, the expanding Regent's Canal Dock had encroached so that the Island was no longer strictly such, and further portions were filled in later in the nineteenth century.
 Even so, traces can still be discerned adjacent Victory Place, Limehouse, which is built on the site.
