Course
The Urugua-í River, also called the Marambas or Grande River, has a length of about 100 km, including the reservoir formed by the Urugua-í Dam. Tributaries include the Sarita River, Arroyo de las Cabeceras and Uruzú River. The Urugua-í River flows through the southern part of the Urugua-í Provincial Park in a southeast – northwest direction and is impounded by the Urugua-í Dam to the west of the park. The park was created in part to compensate for the flooding of 8800 ha of the lower Urugua-í River basin caused by construction of the dam.
