---

Many activities in Maninjau Lake contribute the input of organic and anorganic matter that affects the water quality, especially nutrient concentration in waters. A research aims to understand the trophic state of Maninjau Lake based on TSI has been conducted on January to February 2017. There were 4 stations, namely, Station 1 (bay area), Station 2 (inlet area), Station 3 (fish floating cages area) and Station 4 (outlet area). In each station there were 3 sampling points, in the surface (0.5 m), 2 secchi depth (1.2 m) and 4secchi depth (2.4 m). Sampling was done once/two weeks for 1.5 month period. Water quality parameter measured were total phosphorus, chlorophyll-a, transparancy, depth, temperature, dissolved oxygen, pH. Results shown that the transparancy 45-78 cm, total phosphorus 0.109 – 0.287 mg/L, chlorophyll-a 18.34 – 62.01 μg/L, depth 16.4 m – 52.5 m, temperature 26.5 – 29.2 ºC, pH 6 – 8, dissolved oxygen 0.06 – 9.01 mg/L. Based on the TSI value, the Maninjau Lake was categorized as light eutrophic – heavy eutrophic.
