The Telaga Waja River, flowing down the verdant slopes of Mount Agung in East Bali, is best known today for its rafting adventures but beneath its rushing waters lies a deep, often overlooked historical and cultural undercurrent. Historically, this river has served as both a geographical and spiritual artery for the people of Karangasem. It provides water for rice fields through a traditional irrigation system called subak and many Balinese believe it to be sacred.
