THIS IS BUFFALO CITY: East London is the only South African city which is home to four major rivers.
The biggest of these, the 126km Buffalo River - one of South Africa's largest navigable rivers - has its source high in the Amatola Mountains, at an altitude of 1200m.
It feeds into four dams en route to the sea: Maden Dam, Rooikrantz Dam, Laing Dam and, finally, Bridle Drift Dam, the largest impoundment on the river.
The endangered Border Barb can be found in the waters of the Buffalo River and there is also a small population of the endangered Eastern Province rocky (Sandelia bainsii) in the Yellowwoods River, part of the Buffalo River basin.
