In response to the claim of bad water quality of Lake Toba for an international tourism destination, the government of North Sumatra issued two regulations that determined the improvement of water quality from mesotrophic to oligotrophic and scaling down of carrying capacity from 70 thousand to 10 thousand tons per annum. This regulation provoked conflict between the tourism industry and the fish in-cage farming industry. This study was carried out to verify as to whether the fish in-cage farming industry is the sole major factor in the deterioration of Lake Toba's water quality. Field research was carried out in 2020-2021 at 60 sampling points around Lake Toba. Identified water quality based on nutrients consisting of total nitrogen, total phosphorus, chlorophyll, and water brightness. The study concluded that fish in-cage farming was not the single major factor responsible for the lake's water deterioration. It also concluded the appropriate ceiling production capacity was 67 thousand tons per annum, and the water quality became mesotrophic. Therefore, it recommended the provincial government should change its management approach to controlling pollution entering Lake Toba from an instructive (top-down) to a multi-stakeholder approach called the co-management model.
