The Krom Antonies River is a tributary of the Verlorenvlei River, which is part of the Verlorenvlei catchment. The Verlorenvlei is an estuary system and a natural wetland in the Sandveld.
Groundwater – the basis of the irrigation farming in the area – is extracted from wells. In addition, runoff dams and small dams in the Krom Antonies River are used to collect water for irrigation.
The catchment is part of the G30D Quarternary catchment and therefore managed within the Water Management Area 17, the Olifants/Doorn water management area. A Water User Association was established in the catchment in 2007.
