Pond Lane Flood Gates is a redundant flood defence structure, located near Lea Bridge Road on the River Lee Navigation in the London Borough of Hackney, England.
Lea Bridge Lock was demolished in 1853, and was replaced by Pond Lane Lock at Cow Bridge in 1865, but it was only operational for seven years, as the navigation was rebuilt for larger barges, and was made level between Old Ford and Tottenham.
The structure lasted until 1931, when it was demolished, to be replaced by the Pond Lane Flood Gates, a little further upstream.
[2] The construction of the Thames Barrier caused the flood gates to become redundant and they were finally removed in 1987.
The filter beds were built in 1852, to provide cleaner water to London, as a response to an outbreak of cholera three years before.
