Sediment removal and management

Dredging of the "jelly" layer from the dam wall zone (Figure 2) and of sediments from the Crocodile River inlet zone and river mouth (Figure 3) is considered a priority. Both schemes will be examined through so-called bulk sampling and pilot runs before actual operations will be finally designed and implemented. About 5.85-7.75 ? 10'' m1 of sediments should be dredged/ extracted once-offin order to reduce the historical sediment and internal nutrient load to target levels.
