Geography

The 295-km long San Miguel River rises on the slopes of the Andes Mountains, in the extreme south of the Colombian department of Nariño, on the border between Colombia and Ecuador.^[1] It then flows east, marking the border between the two countries, before passing through Ecuador and then joining the Putumayo River, again on the border, from the left at Puerto El Carmen de Putumayo.^[2]
