Lake Batur of Bangli Regency, Bali, Indonesia, is a 16,05 km2 volcanic endorheic lake utilized for aquaculture. The regional regulation of Bangli Regency stipulates the Lake Batur area as an area developed through aquaculture activities, known as Minapolitan, with a maximum area of 5% of the lake surface. We assessed the suitability of Lake Batur for aquaculture according to water quality data of 2011 and 2017 using Canadian Council of Ministers of Environment (CCME) Water Quality Index (WQI). Water quality parameters considered were pH, DO, N-NH4, N-NO2, N-NO3, P-PO4, TN, TP, TDS, and SO4. The result showed that CCME-WQI in 2017 was higher than in 2011, which implied that the lake water was becoming more unfit for aquaculture and the lake was deteriorating.
