The mean annual runoff of the Sundays River Key Area is 220 million m3/a. The gross available water in the Sundays River, based on current development levels, is estimated to be 12 million m3/a. The available water was determined at the bottom of the catchment and is derived mainly from the natural runoff. There are significant return flows from both irrigation and the mining activities in the catchment. The water availability after accounting for the ecological Reserve and allowing for return flows and groundwater resources is some 8 million m3/a. (Ref 1) | ||||||||||||||||||||||
