The increasing demand for raw water requires a reliable water source in terms of both quantity and continuity. This study aims to analyze the potential discharge of the Bumbula River in Bone-Bone Village, Batukara District, Muna Regency, as a raw water source for the Regional Public Water Company (PDAM). This descriptive quantitative research was conducted in May 2025, collecting primary data through observation, interviews, documentation, and the float method, supported by secondary rainfall data from the Meteorology, Climatology, and Geophysical Agency (BMKG). The study site covers an area of 13.58 km² with a population of 485, located in a humid tropical climate with an annual rainfall of 1,800–2,500 mm and latosol soil type. The river flow discharge measurements at two cross-sections yielded values of 17.46 m³/s (17,460 L/s) at Point A and 15.73 m³/s (15,730 L/s) at Point B, where flow stability is strongly influenced by seasonal rainfall and upstream forest vegetation cover. In conclusion, the Bumbula River possesses highly sufficient potential as a PDAM raw water source even during the dry season, provided that integrated watershed management is implemented to ensure long-term water availability.
