The River Lee Diversion is located in the Lea Valley, close to Enfield Lock and to the north east corner of the King George V Reservoir.
It flows under the North Circular Road at the Lea Valley Viaduct before skirting the western perimeter of the Banbury Reservoir, then flows close and parallel to the River Lee Navigation, passing to the west of the Lockwood Reservoir.
[1] The clean, well-oxygenated, concrete-lined, fast-flowing water provides the ideal environment for the barbel.
Also, of note is the fish-eating bird the goosander which feeds in the river.
[2] Access is limited as the river mainly flows through Thames Water property.
