Alluvial gold dredging notably expanded the drainage basins of these rivers, consequently augmenting water accumulation. Moreover, diversion of river sources to distant locations for gold ore washing further contributed to the rise in water volume. Resultantly, effluents gather on the land and in abandoned mining pits.
