BGCMA is an acronym for Breede-Gouritz Catchment Management Agency and is the lead agent for water resources management within the Breede-Gouritz Water Management Area (BGWMA). The BGWMA is the result of the amalgamation of the Breede WMA and Gouritz WMA. The BGWMA is bounded by the Indian Ocean to the south, the Berg-Olifants WMA to the west, the Orange WMA to the north and the Mzimvubu-Tsitsikamma WMA to the east.
The South African Water Management Areas
The BGWMA falls largely within the Western Cape Province with a small portion of the upper catchment of the Olifants River being in the Eastern Cape Province and tiny portions of the upper catchments of the Gamka and Groot Rivers falling in the Northern Cape Province.
The Provinces Of South Africa
The Breede-Gouritz WMA includes the catchment area of the Gouritz River and its major tributaries (the Gamka, Groot and Olifants Rivers) as well as the catchments of the smaller coastal rivers that lie to the east and west of the Gouritz River mouth, the Breede River and the catchments of the smaller coastal rivers that lie to the west of the Breede River mouth, viz. the Palmiet-, Kars-, Sout-, Uylenkraals-, Klein-, Onrus- and Bot-Swart Rivers. The two large rivers within the BGWMA are the Breede and Gouritz Rivers.
The Breede River, with its main tributary the Riviersonderend River, discharges into the Indian Ocean. The Gouritz River has three main tributaries - the Groot, Gamka and Olifants Rivers. There are a number of other smaller rivers in the BGWMA, viz. the Touws, Duivenhoks, Goukou, Hartenbos, Great Brak, Kaaimans, Knysna and Keurbooms.
