(2) The net contributions to the total net natural mean annual runoff (mean annual runoff in the natural condition without any land and water use effects and allowing for river channel losses) (MAR) of 3 800 million m3 of the Maputo watercourse at the estuary by the various catchments are estimated as follows: Catchment Contributions to MAR (million m3) Mozambique South Africa Swaziland Total Lusushwana Mpuluzi Usuthu Ngwempisi Mkhondvo Ngwavuma Pongola Maputo - - 5 - - - - 100 80 ▇▇▇ ▇▇▇ ▇▇▇ 370 20 1 100 - 340 40 505 210 200 160 60 - 420 260 610 500 570 180 1 160 100 Total 105 2 180 1 515 3 800
(3) The irrigation areas developed by 1995 within the Maputo River Basin are classified into Class 1 and Class 2 categories for the purpose of preferential access to water during periods of low flow and are estimated to be as given in the table below. Class 1 irrigation areas will be supplied with water at a higher assurance of supply than Class 2 irrigation areas. Class 2 irrigation areas will be the first to have their water abstractions and diversions from the rivers reduced and even completely curtailed during the low flow months of the year before any curtailments of the water supplies to Class 1 irrigation areas are considered.
