The Keurbooms River is approximately 85 km long with a catchment area of 1,080 km2. Its main tributary is the Bitou (Bietou).[2]
Ecology
The Keurbooms River marks the eastern limit of the area inhabited by the Cape galaxias(Galaxias zebratus), a South African fish species endemic to the Cape Floristic Region. It shares the same habitat as imported trouts and lives in an area between the Keurbooms and the Olifants River.[3] Although in South Africa this relatively delicate fish is only classified as near threatened, in Australia species of the same genus were driven to extinction by competing salmonids.[4]
