                         is fundamental to determining the most promising strategies to 
                         mitigate eutrophication and its undesirable effects. However, such 
                         analyses are rare in Brazilian urban ponds where water quality 
                         impairment remains a significant issue. We performed a mass 
                         balance to identify the main phosphorus (P) sources in a 
                         hypereutrophic tropical shallow urban pond. We used the PCLake 
                         model to estimate the P loading required to reduce phytoplankton 
                         biomass. The water column was considered the primary unit in the 
                         model. The P balance was calculated from external inputs, internal 
                         inputs from bed sediment to the water column, and outputs from the 
                         water column through surface water outflow and to the bed 
                         sediments over a full hydrological year. The total P input into 
                         the pond water (external and internal) was 35.3 mg m\−2 
                         d\−1 and the output was 35.2 mg m\−2 d\−1. 
                         The P balance revealed that contributions to the water column from 
                         external and internal sources were 82.5% and 17.5%, respectively. 
                         Birds were the main contributor to P input (76.0%). The highest P 
                         loss from the water column was to the sediment (97.6%). Most of 
                         the P leaving the water column to the sediment was retained in the 
                         sediment, and part was returned to the water column through 
                         internal loading. Measures to reduce eutrophication in this pond 
                         should focus on integrated management to decrease both the 
                         external and internal P sources by managing birds and avoiding P 
                         release from sediment, and to decrease water residence time in the 
                         pond.",
