1 | 2021 article | Role of internal and external nutrients loading in regulating in-lake nutrient concentrations in a eutrophic shallow lake Som, Cit Sinang The information on changes in total phosphorus and total nitrogen concentrations of lake in response to variations of different nutrients loading is critical for the selection of an appropriate lake management strategy. This study aimed to evaluate the influence of internal and external nutrients loading in controlling in-lake nutrient concentrations in a shallow lake system. This study was conducted in Slim River Lake for 12 months to quantify internal, external total phosphorus and total nitrogen loading, and in-lake total phosphorus and total nitrogen concentrations. Total phosphorus and total nitrogen in storm water and grab water samples were quantified using ascorbic acid and hydrazine reduction method. Study results indicated that internal total phosphorus and total nitrogen loading fluctuated from 150.17 kg to 7,538.33 kg and 2.72 kg to 42.23 kg, respectively, thus suggesting the significant sediment phosphorus and nitrogen released into the water column.
