The mean annual runoff of the Bushmans
River is 358 million m3/a. The
gross available water resource of the Bushmans River Area, based
on current development levels, is
estimated to be 115 million m3/a. The available
water resource is derived mainly from the Wagendrift
Dam, which is currently underutilised. After accounting
for the ecological Reserve and allowing for return flows and groundwater
resources, there is an estimated 80 million m3/a which can be
used consumptively in the Bushmans
River Area or in the Lower Thukela Area
