Swartkops River, also Zwartskop River, (Afrikaans: black hills) is a watercourse in the Eastern Cape province of South Africa.^[1] The source of the Swartkops is near Cockscombe Mountain,^[2] and it flows east into the Algoa Bay of the Indian Ocean in Bluewater Bay, just outside Gqeberha.^[1] Its two main tributaries are the northern Kwa-Zunga River and the southern Elands River.^[1] The river is also fed by Motherwell Canal, Markman Canal, and Chatty River, which are also sources of water pollution.^[2] The river's Groendal Dam was constructed in 1933. The Swartzkops watershed lies with the Uitenhage Artesian Basin.^[1] The river suffers from sewage pollution, litter, and algae blooms.^[3]
