The Cauca River, which contributes a substantial part of its total flow, rises in the mountains south of Popayán and, after passing through the floor of the Cauca valley near Cali, occupies deep canyons in most of its passage through the departments of Caldas and Antioquia before emerging onto the floodplain of the lower Magdalena.

 Coupling between Annual and ENSO Timescales in the Malaria-Climate Association in Colombia
Malaria in Caucasia exhibits high negative seasonal simultaneous correlations with river discharges of the Cauca river from January to October, but the strongest correlation is observed at lags of 2-4 bimonths (Table 1).
Results suggest that the increase in the number of malaria cases is associated with an increase in air temperature and a decrease in rainfall and river discharges.
This association with a decrease in river discharges is common for localities along wide river floodplains.

Manatee habitat in Colombia is characterized by and including areas of swamps, coastal lagoons and creeks and turbid, sluggish rivers with abundant floating meadows (INDERENA 1993 unpbl report).
Manatee habitat in Colombia is under continuous degradation due to increasing human settlement in coastal areas, transformation of certain areas into agricultural and cattle-raising land, contamination and eutrophication, drainage and rerouting of water bodies and subsequent sedimentation of creeks and rivers, which impairs natural migration of the aquatic species in the area.
The Colombian government has set aside a number of sanctuaries and parks for the protection of its wildlife, and in a number of them the manatee is being protected.
