Pollution may result from mine sludge and affect the functioning of the river system when exposed soil is blown in the wind and can have a significant impact on aquatic populations further affected by dam building in the region. Dams may have a profound impact on migrating fish and ecological life and leave plains prone to flooding and leaching.
