The Lee Valley Reservoir Chain is located in the Lee Valley, and comprises 13 reservoirs that supply drinking water to London.[1]
The Reservoir Chain, together with the flood plain which it occupies, is a major geographic constraint; together with the Thames it is one of the two significant topographic features that divide the capital and define the communities on either side. The Lower Lea Valley, downstream of the reservoirs, is more integrated, with better east–west transport connectivity.
