Human Made Basins

Human activity has also played an important role in the development of lake basins all over the continent. Strip mining and road construction has produced a large number of artificial excavations. Once abandoned and flooded, these depressions form lakes. One example is Topibo Meer in Suriname, which is a large red-mud lake complex at an old mine site near Paranam. Nevertheless, the damming of streams and rivers has been, and continues to be, the most important human action responsible for the origin of lake basins throughout South America. Many artificial lakes have been constructed to serve as water supplies, to provide power, to aid in navigation, to increase the supply of fish and as other aquatic products or for defense.
