Sutami Reservoir is one of the largest reservoirs in East Java Province and is very useful in the life of people in Malang. However, the water quality of Sutami reservoir currently degrades due to waste. This study aims to determine water quality using the pollution index method and mathematical modeling. Polynomial regression is the most suitable mathematical model. It was obtained by statistical testing and adjusted based on population index data. Sutami Reservoir is classified as a reservoir with a eutrophic trophic status. The load capacity in eutrophic conditions at the monitoring station revealed that the levels exceeded the maximum pollution load limit. The relevant authorities need to take action to overcome the waste problems which contribute to the degradation of water quality in Sutami reservoir.
