Considering its rugged topography, the province developed complex arteries of rivers, streams, creeks and springs. One major stream is the Magat River with its four tributaries, namely: Matuno, Sta. Fe, Sta. Cruz and Marang Rivers with combined drainage area of 178,400 hectares or its equivalent 1,784 sq. kms. These rivers are characterized by steep gradient on the upstream and slightly decreasing gradient towards the downstream.
The upper catchment of Matuno and Sta. Cruz rivers is the Cordillera Mountain Ranges situated in the western part of the province. These two (2) tributary rivers traverse the municipalities of Ambaguio and Kayapa. While the Sta. Fe and Marang Rivers originate in the eastern slopes of the Caraballo Mountains flowing towards Bagabag and ultimately to the reservoir of Magat high dam in Ramon, Isabela.
On the other hand, the Tubo and Casecnan Rivers are located at the southeastern part of the province and serve as the headwater of the Cagayan River. The Casecnan River including some portions of the Quirino Province has a total drainage area of 609.17 sq. kms.
Generally, the province is well drained except in low-lying areas where flash floods commonly occur during the rainy season due to overflowing of rivers caused by heavy siltation of riverbeds.
