River course
The Río Santiago arises in the sub-Andean mountain region at the confluence of the Río Zamora (right) and Río Namangoza (left). It initially flows 65 km in an easterly direction through the Ecuadorian province of Morona Santiago . The trunk road E40 to Puerto Morona follows the course of the river. The Río Yaupi flows into the river from the north. This then crosses the border to Peru and flows on the remaining stretch of the river in a southerly direction through the Amazon lowlands of the Condorcanqui province . Puerto Galilea , the administrative seat of the Río Santiago district , is located at river kilometer 55 on the right bank of the river. The Río Santiago finally meets the flowing eastward Río Marañón, 7.5 km above the Engpaßstelle Pongo de Manseriche .
Protected areas
The National Park Ichigkat Muja - Cordillera del Condor is located in Peru along the border west of the Río Santiago. A ridge separates the lower reaches of the Río Santiago from the further east running Río Morona . The Santiago Comaina Conservation Area extends over this ridge.
Hydrology
The Río Santiago drains an area of 33,640 km². Of these, 26,176 km² are in Ecuador. The mean discharge is 1780 m³ / s.
