lies west of the coastal town of Mossel Bay in the Western Cape. The river is approximately 67 km long with a catchment area of 1 550 sq. km. Agriculture accounted for about 35% of the land-cover of the Goukou catchment. This comprised a mixture of temporary commercial dryland agriculture, commercial forestry, temporary commercial irrigated agriculture, and improved grassland. About 2% of the catchment was degraded shrubland while approximately 63% was natural. Natural land-cover consisted of shrubland, grassland and grassland with some waterbodies and wetlands. Urban development accounted for about 1% of the land-cover and comprised mainly residential and industrial development associated with the coastal settlement of Still Bay and the town of Riversdale inland.
