The Gamtoos has the fourth largest catchment of all the Cape rivers, with an area of 34 438 km2 which extends right up into the Great Karoo. Two large tributaries drain the eastern extremity of the Nuweveld Mountain range and the western slopes of the Onder-Sneeuberg mountain ranges of the great escarpment above Nelspoort and Murraysburg. The geology and geomorphological features of the Gamtoos Estuary and adjacent shoreline have been described by the City of Port Elizabeth's metropolitan Planning Unit in the coastal study undertaken in 1978. Because of the size and diversity of the entire system it has not been possible to include details of all the available information of the Gamtoos River.
