The Kapuas River, with a length of approximately 1,143 kilometers, is the longest river in Indonesia and the primary river system in West Kalimantan on the island of Borneo. Originating in the Müller Mountains in the center of the island, it flows westward until it empties into the South China Sea near Pontianak. The river is a vital transportation artery for moving timber, minerals, and agricultural products, and serves as the main water source for millions of people. Its waters are home to over 700 species of fish, including many rare and economically significant species. The region along the river hosts extensive swamp and rainforest habitats, which are increasingly threatened by mining and plantation industries. Culturally, the river is deeply connected to the Dayak people, who have lived along its banks for centuries.
