Location

At its source the streams of Castillume and Colchane flow to the south, while to the north the river flows to Sallire. Downstream, a kilometer before reaching Colchane, it is joined to the north by the Aroma stream that contributes 120 L/s and the Cotacahue stream that brings 100 L/s to the south to complete the beginning of the Tarapacá ravine. Two kilometers upstream from Sibaya it is joined by the Siyajualla (or Jellajella) ravine to the south, which usually does not bring water but provides an important flow in times of flood. In Sibaya the stream is narrow.
