The Sundays River or Nukakamma is a river in the Eastern Cape Province of South Africa. It is said to be the fastest flowing river in the country. The Khoisan people originally named this river Nukakamma because the river's banks are always green and grassy despite the arid terrain that it runs through.Presently this river is part of the Fish to Tsitsikama Water Management Area.CourseThe source of the long Sundays River is in the Sneeuberge (the highest mountain range in the former Cape Province) near Nieu-Bethesda. The river then flows in a general South/Southeasterly direction, passing the town Graaff-Reinet in the Karoo before winding its way through the Zuurberg Mountains and then past Kirkwood and Addo in the fertile Sundays River Valley. It empties into the Indian Ocean at Algoa Bay after running through the village of Colchester, 40 km east of the city of Port Elizabeth. Dams Darlington Dam Nqweba Dam
